Using Plants, Astronauts Could Create Their Own Medicine

A new pharmaceutical production method could allow astronauts on long space missions to "grow" fresh medicines on demand using plants. The work could also bring low-cost pharmaceutical production to resource-limited areas on Earth. from Universe Today https://ift.tt/6ERhq2O via IFTTT

Astronomers Want to Build a Swarm of Telescopes to Find LIFE

Current plans for flagship telescopes in the 2040s are focused on answering a simple question - are we alone? Our best telescopes to date, such as the James Webb Space Telescope (JWST) have only given us tantalizing glimpses into the atmospheres or other worlds, but not enough to truly determine whether or not life as we know it exists there. Astronomers have been waiting for technology to catch up to their dreams of what is possible in terms of new types of telescopes, and recently the W.M. Keck Institute for Space Studies released a report detailing the Large Interferometer For Exoplanets (LIFE) mission, which they hope will help provide a definitive answer to that simple question. from Universe Today https://ift.tt/6O5LNSd via IFTTT

Plutonium in Earth Rocks Signals Long-ago Cosmic Collision

A small lump of rock pulled up from the Pacific Ocean seafloor in 1976 is giving scientists new clues about an ancient cosmic event. More than a hundred million years ago, two neutron stars collided. The resulting energetic kilonova sent a rain of long-lived elements, such as isotopes of plutonium, through space. Eventually, this stellar "debris" settled onto Earth. Some sank to the bottom of the ocean and got incorporated into a chunk of ferromanganese rock. Hidden inside were a few hundred atoms of plutonium radioisotopes. They provide the strongest clues about what created them in the merger and how long ago it happened. from Universe Today https://ift.tt/NwkYc81 via IFTTT

What Would Happen if the Sun Stopped? Part 4: Black Hole Sun

Switch off fusion and, for ten thousand years, nothing happens. Then the Sun begins a slow, strange death: shrinking, briefly brightening, and coasting on gravitational heat for tens of millions of years. And the neutrinos give the whole thing away in just eight minutes. from Universe Today https://ift.tt/iWD81Qb via IFTTT

What Would Happen if the Sun Stopped? Part 3: The Photon Traffic Jam

A photon born in the Sun's core takes around 100,000 years to fight its way to the surface, bouncing through a random walk so inefficient that the light on your face is older than human civilization. Why the Sun's surface is a hundred-millennia-delayed broadcast. from Universe Today https://ift.tt/6wRrKjC via IFTTT

'High-Res' is the Secret to Finding Alien Life with the Next Great Space Telescope

We’re still in the definition phase of the Habitable Worlds Observatory (HWO), but it seems like every week a new research group comes out with a paper helping to contribute to what is shaping up to be one of the most important space telescopes of the 2040s. A new paper from a team of researchers led by Daniel Jaffe of the University of Texas at Austin contributes to this ongoing definition work by arguing that it’s time HWO adopted a high-resolution near-IR spectroscopy capability, - which sounds great in practice, but so far hasn’t been attempted due to technological limitations. But, according to the paper, two recent inventions finally make a working version of an extremely high resolution exoplanet hunter viable. from Universe Today https://ift.tt/GOyfBsj via IFTTT

Lava planet has hydrogen-rich, active atmosphere

It’s 2158, and you’re chugging away on your PhD in Planetary Volcanology from the University of Utopia Planitia on Mars. Graduate students still get paid a sub-living wage, so you’ve been stuck eating freeze-dried ramen for the past three years. You’ve completed studying Jupiter’s moon, Io, but now you have to leave the solar system for a good exoplanet analog. While Io’s volcanism is caused by tidal heating, you need an exoplanet whose volcanism is caused by extreme heat from its host star. You recently secured funding from the Exoplanet Research Institute for a faster-than-light (FTL) ship, but the exoplanet is required to be less than 50 light-years away. from Universe Today https://ift.tt/GIB4ZsS via IFTTT

What Would Happen if the Sun Stopped? Part 2: Kelvin and Helmholtz at the Ready

How can the Sun keep shining with its furnace switched off? Two nineteenth-century aristocrats, Helmholtz and Lord Kelvin, worked out the answer mostly by accident. It comes down to stored heat, gravitational shrinking, and the strange self-regulating thermostat of hydrostatic equilibrium. from Universe Today https://ift.tt/uVPatAY via IFTTT

Are Alien Probes Hiding in Our Backyard? A New Study Says We’ve Barely Looked

Even at this early stage in our space faring age, humanity has already begun sending probes that will eventually reach other solar systems, even if that was not their original intention. Five robotic explorers - Pioneer 10 and 11, Voyager 1 and 2, and New Horizons - are all on escape velocities out of the solar system, and might someday enter another one. They will no longer be operational at that point, but they serve as a proof of concept that spacefaring civilizations do indeed build interstellar probes. Which raises the obvious question - has anyone else sent their own robotic explorers to ours? In a recent paper, published in the Proceedings of the IAU Centenary Symposium, astronomer T. Joseph W. Lazio, points out a painful truth - we still have no idea, and our technology will need to get much better if we plan to find out. from Universe Today https://ift.tt/cFT2gdt via IFTTT

The Best Place to Look for Alien Megastructures Might Be Moon Dust

Our search for technosignatures - clear signs of advanced civilizations beyond Earth - takes many forms. Many are driven by the famous Drake equation, which attempts to estimate how many technological civilizations there are in the Milky Way. However, there’s a big fat question mark at the end of that equation in the form of a variable intended to account for the “longevity” of a civilization. And to be clear, that doesn’t mean how long the civilization itself survives. It simply means how long it actively creates a signature that is detectable by our current technology. A new paper, available in pre-print on arXiv from Oxford astrophysicist Brian C. Lacki, argues that, since the chances of us overlapping in time with any such civilization are miniscule, we’re much more likely to find the ruins of a “dead” civilization - and, surprisingly, the best place to do so might be in our own solar system. from Universe Today https://ift.tt/NoqE1gj via IFTTT

LISA Could Double as an Asteroid Scale

One of the hardest things to calculate for an asteroid is its mass - but it is such a critical feature. It determines how much of an impact it would have if it hits something, or how many resources are potentially available on it. But to accurately measure it we typically use optical sensing and a guesstimate of its density based on its spectral profile. A new paper suggests a completely novel way to use the Laser Interferometer Space Antenna (LISA) flagship mission to potentially provide highly accurate mass calculations for nearby asteroids without any change in hardware. from Universe Today https://ift.tt/qkZIXrx via IFTTT

The Galaxy's Spin Is Hiding in the Hum of Gravitational Waves

We are used to thinking of gravitational waves as messengers from catastrophes in space, the ringing of spacetime after black holes collide for example. But our own Galaxy hums with a fainter, steadier signal, a chorus of millions of unseen binary stars. A new study has found that this hum carries a hidden fingerprint of the Milky Way's spin, and that if a future space mission ignores it, our picture of the Galaxy itself could come out subtly wrong. from Universe Today https://ift.tt/K6SXdxF via IFTTT

JWST Finds Exoplanets Choked by Diesel Smog

It’s 2134, and humanity has finally embraced green technologies while ridding the Earth of harmful fossil-burning technologies, most notably gasoline, wood, coal, and oil. As a result, soot has been rendered obsolete, and all commercial products from soot, including shoes, wires, computer products, and eye products, are now produced from eco-friendly technologies. However, the uber-rich who still fancy non-eco-friendly products are willing to pay soot’s weight in gold for it. Therefore, the Exoplanet Research Corporation outfits its best ship to search for soot-enriched exoplanet atmospheres. from Universe Today https://ift.tt/pYje5Nl via IFTTT

NASA Study Challenges Theories on Where the Ingredients for Life Came From

NASA-supported scientists have provided new information about how the early Earth may have acquired some elements necessary for the planet to become habitable.

Titan's Hidden Blanket

Saturn's moon Titan has long fascinated scientists, it’s a world with rivers, lakes, and a thick atmosphere, all made not of water but of methane. Now, a new study suggests Titan is stranger than first imagined since beneath its surface lies a 9 km thick crust of methane laced ice that acts like a giant thermal blanket, warming the interior in ways nobody expected. from Universe Today https://ift.tt/TKRxdSA via IFTTT

Neptune’s Weirdest Moon Nereid Might Be the Lone Survivor of an Ancient "Moonpocalypse"

Neptune is definitely the odd one out of the gas giants. It’s tilted at a strange angle, and its moons are completely different from any other gas giant we know of.

The Hidden Physics Complicating Interstellar Lightsails

If we’re to reach another star, chemical propulsion will not get us there in any reasonable time frame. We’re going to need a different propulsion technology, and one of the most promising seems to be a solar sail. These giant reflective surfaces form the basis of many interstellar missions. Combined with giant lasers pushing them, they can be accelerated to speeds unreachable by any other current technologies. However, according to a new paper available on arXiv from Chao Shen and Jiaze Li of the Harbin Institute of Technology, once those missions start reaching a significant percentage of the speed of light they’re going to run into a drag force from the light itself. from Universe Today https://ift.tt/RyKlnWT via IFTTT

The SETI Institute Releases Technosignature Report on 3I/ATLAS

Scientists at the SETI Institute searched for technological signals from 3I/ATLAS, the third interstellar object observed in our Solar System. Using the Allen Telescope Array (ATA) at the Hat Creek Radio Observatory in Northern California, the team scanned a wide range of radio frequencies for signs of extraterrestrial technology and found none, as expected based on other astronomical observations showing that the object exhibits natural comet-like composition and behavior. “Eventually, our own Voyager spacecraft will be extraterrestrial artifacts in other stellar systems,” said Dr. Sofia Sheikh, lead author on the paper. “Given that, it is important that we understand the natural distribution of interstellar objects so that we will be able to identify any anomalies that could one day be signs of an artificial interstellar object.” The team observed 3I/ATLAS for more than seven hours with the ATA, covering 1 to 9 gigahertz. This broad range allows scientists to search for narrowband ...

New Cloud-Detecting Method Will Help Astronomers Characterize Exoplanets

Astronomers have developed a technique that allows them to detect cloud cycles on distant exoplanets. Using data from the James Webb Sapce Telescope (JWST), the astronomers found that mornings and evenings on the gas giant WASP-94A b have extremely different weather patterns: mornings are riddled with sand clouds, while the skies are clear in the early evenings. By isolating the clouds, researchers can more accurately measure a planet’s atmosphere and provide a clearer picture of the planet’s composition. WASP-94A b, for example, has much less oxygen and carbon than astronomers perviously calculated, making its atmosphere much more like Jupiter than they had originally thought. from Universe Today https://ift.tt/y7A40gE via IFTTT

Even Without A Magnetosphere, Mars Can Still Deflect Some Solar Wind

Flash-Melted Glass from Chang'e-5 Reveals a High Levels of Iron on the Moon

It might not seem like it, but the Moon is constantly being both sandblasted and baked. Its lack of a thick atmosphere allows micrometeorites to impact the surface at speed, and the solar wind isn’t held back either, baking the regolith with a constant flow of high-energy particles. These processes drive what is called “space weathering”, and it can drastically alter the physical and chemical properties of the lunar dirt over the course of billions of years. And we’re finally getting a better sense of what that means in practice thanks to two new papers from researchers at the Chinese Academy of Sciences and Peking University, which used advanced electron tomography and spectroscopic techniques to analyze samples returned from the Chang’e-5 mission to the near side of the Moon. from Universe Today https://ift.tt/1HoeGrJ via IFTTT

Astrobiology's Looming Statistical Crisis

Multi-billion dollar space telescope programs aren’t only feats of aerospace engineering. They also feature “lies, damn lies, and statistics”. Or at least statistics. They definitely feature those, as does all good observational astronomy. The problem with statistics is, in order to get a clear definitive answer, you need lots of samples. And, to put it mildly, it’s hard to find lots of samples of planets with alien life on them. And even harder to prove that the signals we think are caused by alien life aren’t caused by some other non-biological process. Or at least that’s the theory underpinning a new paper available in pre-print on arXiv from David Kipping of Columbia University (and Cool Worlds YouTube fame). from Universe Today https://ift.tt/dhR1aS9 via IFTTT
