Correcting Radius Biases in TESS Exoplanet Discoveries

How accurate are the exoplanet radius measurements obtained by NASA’s Transiting Exoplanet Survey Satellite (TESS)? This is what a recent study accepted to The Astrophysical Journal hopes to address as a team of researchers investigated how hundreds of exoplanetary radii measured by TESS during its mission might be incorrect and the data could be underestimating the radii measurements. This study has the potential to help astronomers develop more efficient methods more estimating exoplanetary characteristics, which could influence whether or not they are Earth-sized. from Universe Today https://ift.tt/8Fj2Emk via IFTTT

GJ 12 b: Earth-Sized Planet Orbiting a Quiet M Dwarf Star

What can Earth-sized exoplanets teach scientists about the formation and evolution of exoplanets throughout the cosmos? This is what a recently submitted study hopes to address as an international team of researchers announced the discovery of an Earth-sized exoplanet that exhibits temperatures and a density comparable to Earth. This study has the potential to help scientists better understand the formation and evolution of Earth-sized exoplanets and what this could mean for finding life beyond Earth. from Universe Today https://ift.tt/MnciQkl via IFTTT

The Oceans on Enceladus Are Highly Alkaline

What can the pH level of the subsurface ocean on Enceladus tell us about finding life there? This is what a recent study accepted to Icarus hopes to address as a team of researchers investigated the potential pH level of Enceladus’ subsurface ocean based on current estimates. This study has the potential to help scientists better understand the composition of Enceladus’ subsurface ocean and what this can mean for finding life as we know it. from Universe Today https://ift.tt/VDmaiAY via IFTTT

Worldwide Team of Citizen Scientists Help Confirm a Tricky Exoplanet

Distant exoplanets can be dodgy to spot even in the best of observations. Despite the challenges, a team of astronomers just reported the discovery of a gas giant exoplanet that lies about 400 light-years from Earth. It's called TOI-4465 b and it takes 12 hours to transit across the face of its star during its 102-day orbit. from Universe Today https://ift.tt/ihHkoB0 via IFTTT

In Situ Resource Utilization and the Importance of Lunar Ice for Artemis III

What is the importance of studying and utilizing lunar polar volatiles during the Artemis program, and specifically for first crewed mission, Artemis III? This is what a recent study presented at the Lunar and Planetary Science Conference hopes to address as an international team of researchers investigated using lunar polar volatiles for in situ resource utilization (ISRU) purposes. In geology, volatiles are substances that vaporize at low temperatures, and examples include water, carbon dioxide, and sulfur dioxide. In the case of the Moon, key volatiles are water located in permanently shadowed regions (PSRs) at the lunar south polar region. from Universe Today https://ift.tt/n06z8tp via IFTTT

A Supermassive White Dwarf Is Pulsating Rapidly, Revealing Details Of Its Interior

Scientists are constantly finding new ways to look at things, and that’s especially true for objects that represent an outlier of their specific type. Adjectives like “biggest”, “brightest”, or “fastest spinning” all seem to attract scientific studies - perhaps because they’re an easier sell to funding agencies. No matter the reason, that means we typically get a lot of good science on specific objects that represent their particular class of objects well, and a new paper from Ozcan Caliskan from Istanbul University in Turkey hits that nail on the head when it comes to the most massive known white dwarf star. from Universe Today https://ift.tt/MsFEutb via IFTTT

How to Make Building Blocks for a Lunar Habitat

The challenge of building habitats on the Moon is considerable, mainly because most additive manufacturing (aka. 3-D printing) techniques are not feasible. By utilizing a 3-D printing method known as light-based sintering, future missions to the Moon could manufacture bricks out of lunar regolith, rather than trying to build whole structures. This would facilitate a long-term human presence on the lunar surface, consistent with the Artemis Program and other plans for lunar exploration and development. from Universe Today https://ift.tt/Bd0tsPN via IFTTT

The Presence of Certain Minerals May Explain Why the Lunar Farside and Nearside are so Different

Why does the Moon have two different faces?. That question frames the lunar dichotomy: The nearside that faces us is different than the lunar farside. Scientists have worked hard to understand why that is, and new research says that the presence of certain minerals could explain why. from Universe Today https://ift.tt/m9bjl61 via IFTTT

Cryovolcanism and Resurfacing on Pluto’s Largest Moon, Charon

What processes during the formation of Pluto’s largest moon, Charon, potentially led to it having cryovolcanism, and even an internal ocean? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as a team of researchers investigated the formation and evolution of Charon to ascertain whether it once possessed an internal ocean during its history and if this could have led to cryovolcanism based on images obtained by NASA’s New Horizons probe. from Universe Today https://ift.tt/F91CWIS via IFTTT

New Propulsion Systems Could Enable a Mission to Sedna

The dwarf planet Sedna will reach its closest point to the Sun in 2075, the ideal time to send a mission to study this world that takes 11,000 years to orbit the Sun. In a new paper, researchers consider two exotic propulsion systems for a mission like this: a direct fusion drive, and an enhanced solar sail. Both methods could allow a spacecraft to reach Sedna in under a decade of flight time. from Universe Today https://ift.tt/ES5HcA2 via IFTTT

Growing Building on Mars with Lichen and Bacteria

When humans finally reach Mars, they're going to rely on local resources for habitat construction. Researchers are considering how Martian explorers could use lichen and bacteria together with Martian regolith to form building materials. These biomaterials can glue together particles of crushed rock into a building material which can then be 3D-printed into houses, furniture and other buildings. This system might only require regolith, air, light and an inorganic medium to create the building material. from Universe Today https://ift.tt/H8EkTBg via IFTTT

A New Way to Detect Primordial Black Holes Through Their Hawking Radiation

Scientists propose a revolutionary new method to detect primordial black holes by hunting for their Hawking radiation. Instead of searching for faint background signals, researchers suggest using the Alpha Magnetic Spectrometer on the International Space Station to watch for distinctive spikes in positron particles as these ancient black holes pass through our solar system, emitting Hawking radiation. from Universe Today https://ift.tt/I5C9FJA via IFTTT

Webb Directly Images A Saturn-Sized Star In A Nearby System

One of Webb’s strong points is its ability to directly image planets around another solar system. The telescope has been in operation for long enough now that a flood of those images are starting, as more and more systems come under the telescope’s gaze. One of those is described in a recent paper and press release from NASA. According to the paper, the planet in a nearby system is about the size of Saturn, which would make it the smallest planet ever found by direct observation. from Universe Today https://ift.tt/C7BIi5V via IFTTT

A fast radio burst detected last year turned out to be from long-dead NASA satellite

A team of astronomers and astrophysicists affiliated with several institutions in Australia has found that a mysterious fast radio burst (FRB) detected last year originated not from a distant source, but from one circling the planet—a long-dead satellite. The team has posted a paper outlining their findings on the arXiv preprint server. from Universe Today https://ift.tt/H6r7958 via IFTTT

Webb Should Be Able to Detect Exo-Jupiters and Exo-Saturns

JWST is a powerful telescope and has directly observed a handful of exoplanets. But according to a new paper, it could set its sights higher, way higher. Astronomers suggest that Webb's MIRI and NIRCam instruments have the capabilities to detect planets around nearby stars as cold (or colder) than Saturn, at the same orbital separation, mass, and age as Saturn and Jupiter. They also found that clouds can have a big impact on their ability to study the planets, but it's easier for MIRI. from Universe Today https://ift.tt/lTYWgZN via IFTTT

NASA’s LRO Views ispace HAKUTO-R Mission 2 Moon Lander Impact Site

The Japanese ispace HAKUTO-R Mission 2 was supposed to touch down gently on the Moon on June 5, 2025. Unfortunately, communications with the RESILIENCE lander were lost about 90 seconds before it should have landed, and it was assumed to have crashed on the lunar surface.

The First Pictures from Vera Rubin are Here!

I can recall the excitement of waiting for the first CCD Image I had taken to download, THAT was exciting. I was using a Starlight Express MX716 for those who can remember. This however is far more exciting. The Vera C. Rubin Observatory has officially come online and now we're looking at its first pictures. The telescope has completed ten hours of test observations, viewing millions of galaxies and Milky Way stars. It found thousands of new asteroids in just a few hours of observations, and took incredible pictures of the Triffid and Lagoon Nebulae. Over the course of its 10-year primary mission, it'll capture 800 images of every spot in the southern sky. from Universe Today https://ift.tt/xcih2qJ via IFTTT

LISA Construction Begins

After years of research, and a completed pathfinder mission, the European Space Agency has officially begun the construction of the Laser Interferometer Space Antenna (LISA). This will consist of three spacecraft flying in formation, sending laser signals back and forth to detect passing gravitational waves - including previously undetected supermassive black hole mergers. ESA has chosen OHB System AG to construct the spacecraft, which are due to launch in 2035 on an Ariane 6 rocket. from Universe Today https://ift.tt/4S3kgUE via IFTTT

There's Ice on Mars, Just Under the Surface

Mars holds two of humanity's greatest space ambitions, discovering alien life and establishing our first foothold on another world. Key to both is the discovery of water. We know it's at the poles, but where could we find it at lower latitudes? In a new paper, researchers carefully examined images of Mars taken by the Mars Reconnaissance Orbiter. They found examples of features, like "brain coral terrain", expanded craters, and ridges which are evidence of water ice just under the surface. from Universe Today https://ift.tt/80R1wfJ via IFTTT

Rare Conditions Can Make Double Hot Jupiters

The Solar System lacks hot-jupiters, intensely hot gas giant planets, so close to their stars they take just days or even hours to orbit once. But there are some systems that have not one, but two hot-jupiters. In a new study, researchers show the long-term gravitational interactions with binary stars that can push multiple gas giants into these extremely close orbits around their stars. Both stars can end up with hot-jupiters. from Universe Today https://ift.tt/4MIxWRL via IFTTT

There's a Link Between the Earth's Atmosphere and its Magnetic Field

The Earth's magnetosphere is a giant magnetic field that arises from the flow of material deep inside the planet. Because the flow of material isn't constant, the strength and shape of the magnetosphere can change over geologic time. But researchers have found that changes in the magnetosphere seem to be correlated with fluctuations in the amount of oxygen in the Earth's atmosphere. Both could be responding to a single underlying process. from Universe Today https://ift.tt/cCvPLWu via IFTTT

Honda - Yes, Honda - Tests a Reusable Rocket

Just when you thought the race to reusable rockets was all wrapped up, a new competitor emerges from the shadows. Honda R&D Co (a subsidiary of Honda Motor Co) successfully tested their new experimental reusable rocket.

The flight lasted for 56.6 seconds. from Universe Today https://ift.tt/bWDQ5CS via IFTTT

Superdense Star Factories Tell a Tale of Starbirth in the Early Universe

The early Universe was a busy place some 13 billion years ago. That's when countless young galaxies began to evolve and birthed stars at a prodigious rate. The hearts of those very distant galaxies show turbulent, lumpy disks studded with even thicker clumps of dust and gas that spawned huge batches of stars. Astronomers want to understand what's driving the clumping, so they've turned to recent surveys of closer galaxies in the "local Universe" that contain similar lumpy regions. from Universe Today https://ift.tt/frk68QW via IFTTT

Vast Filament of Hidden Matter Seen for the First Time

More than one third of the regular matter in the Universe is missing (we're not talking about dark matter, just regular matter). It's needed to make the current cosmological models work, so astronomers continue to search for it, and have found many indirect examples of it. Now a team of astronomers has directly observed it as a huge filament of hot gas bridging four galaxy clusters and containing 10 times the mass of the Milky Way. from Universe Today https://ift.tt/cVdRzPx via IFTTT

A Way to Directly Measure Hawking Radiation

Stephen Hawking has made a compelling case that black holes eventually evaporate, but the time scales are beyond our ability to detect it. A new paper suggests that primordial black holes passing through the Solar System could be releasing positron emissions that would be detectable when they pass up to 10 AU from Earth. If found, they would confirm Hawking's theories and provide an explanation for dark matter. Unfortunately, our best technology isn't quite sensitive enough. from Universe Today https://ift.tt/OW2sVIa via IFTTT

Fast Radio Bursts are Helping to Locate the Universe's Missing Matter

You're probably aware that most of the matter of the Universe is "dark matter," and astronomers still don't know what it is. But 75% of the regular matter in the Universe is also hidden, located in the thin gas between galaxies. Probing this gas is difficult, but astronomers have used a new technique, analyzing the light from fast radio bursts as they pass through billions of light-years of gas. Longer, redder wavelengths are slowed down compared to shorter, bluer wavelengths, allowing the hidden material to be weighed. from Universe Today https://ift.tt/Gc5D9zs via IFTTT

Supermassive Black Hole Has More Material Than it Can Consume

Black holes can accumulate planets and stars' worth of material, but even they have their limits. Astronomers have discovered a supermassive black hole which has reached that limit. Excess material is now being ejected from the vicinity around the black hole at nearly a third the speed of light. Astronomers found that about 10 Earth masses of material were added to the black hole's vicinity in 5 weeks, creating a ring of matter and feeding the outflow jets. from Universe Today https://ift.tt/ShD1uqK via IFTTT

The First Images from Vera Rubin are About to Drop

The Vera C. Rubin is a game changing observatory that we've been keeping our eyes on.

Lunar Dust is Bad. But Not as Bad as Living in the City

When the Apollo astronauts returned to Earth, they complained that the gritty lunar dust got into everything, including their lungs. There have been decades of research into its toxicity, and a recent study has shown that it might actually be less hazardous than regular Earth-based air pollution. Sure, it can cause irritation to lung tissue, but not that kind of severe cellular damage or inflammation seen from urban Earth dust. It doesn't seem to cause long-term diseases like silicosis. from Universe Today https://ift.tt/PCKlqFS via IFTTT

Webb Shows That Young Stars Inherit Their Water From the Cosmos

The early Solar System was filled with both hydrogen and oxygen that can chemically bond into water. But did we create all the water, or was some of it inherited from the earlier times, already present in the protostellar nebula? Astronomers have used the James Webb Space Telescope to study a newly-forming protoplanetary system called L1527 IRS, which will eventually become a star like our Sun. They found evidence that water from interstellar space is preserved when it becomes part of a new star system. from Universe Today https://ift.tt/2SJkg0n via IFTTT

Exoplanetary Systems are Diverse. Our Search for Life Should Be the Same

With over 5,000 exoplanets now identified, astronomers have found that our Solar System isn't the only model of planetary formation. There are super-Earths, sub-Neptunes, hot-Jupiters, and Earth-sized worlds orbiting around red dwarf stars. In a new paper, researchers propose how the search for life could adapt to these bizarre environments, expanding the definition of a habitable world. Life could exist without a surface, or using different kinds of solvents than water. from Universe Today https://ift.tt/kBCVPu6 via IFTTT

Spaceflight Could Be Bad For Your Teeth

Great, another potential long-term risk of spaceflight. Researchers have studied the effects of simulated microgravity on mice and found that it could lead to periodontitis, where the gums become inflamed and the bones supporting teeth start to break down. This was compared to mice who experienced normal gravity. This could be limited to just the teeth or a larger indicator of inflammation in the body caused by weightlessness, which could have other health impacts. from Universe Today https://ift.tt/TeBgVoy via IFTTT

Have Stellar Flybys Altered Earth's Climate in the Past?

If our Solar System seems stable, it's because our short lifespans make it seem that way. Earth revolves, night follows day, the Moon moves through light and shadow, and the Sun hangs in the sky. But in reality, everything is moving and influencing everything else, and the fine balance we observe can easily be disrupted. Could passing stars have disrupted Earth's orbit and ushered in dramatic climatic changes in our planet's past? from Universe Today https://ift.tt/HE8aKez via IFTTT

Astronomers are Closing in on the Source of Galactic Cosmic Rays

In 1912, astronomer Victor Hess discovered strange, high-energy particles called "cosmic rays." Since then, researchers have hunted for their birthplaces. Today, we know about some of the cosmic ray "launch pads", ranging from the Sun and supernova explosions to black holes and distant active galactic nuclei. What astronomers are now searching are sources of cosmic rays within the Milky Way Galaxy.

A Better Way to Turn Solar Sails

Solar sails are space's ultimate free ride, they get their propulsion from the Sun, so they don't need to carry propellant, but they come with their own challenges. A sail has a large surface area but a low mass, which creates a huge moment of inertia and makes it difficult to control, especially with reaction wheels. A team of engineers have cracked it though with "smart mirrors" that can instantly switch their reflectivity on command, transforming sunlight from an unruly force into a precision steering tool. from Universe Today https://ift.tt/t4VMz5J via IFTTT

Webb Sees the Galaxies that Cleared Out the Cosmic Fog

The early universe was shrouded in darkness. Just hundreds of millions of years after the Big Bang, a thick fog of hydrogen gas choked the cosmos, blocking light from traveling far. At some point, this gas became ionized, stripped of its electrons. Thanks to the James Webb Space Telescope, astronomers have identified the culprit: low-mass starburst galaxies emitting huge amounts of ultraviolet light. In just one patch of sky.
