The "Shadow Blaster" Galaxy's Role in High-energy Cosmic Neutrinos

On September 22, 2021, the IceCube Neutrino Detector in Antarctica caught a blast of neutrinos as it passed through the solar system. These neutrinos were remarkably high-energy and came from a galaxy 11 billion light-years away. That's a period of the Universe's history known as "Cosmic Noon". It's when star formation in galaxies was at its most active and that provided an interesting clue to their origin. The source of the neutrinos was nicknamed "Shadow Blaster" because the event that created the neutrinos was hidden by a dense cloud of dust, which made it invisible to optical observations. from Universe Today https://ift.tt/JyNlRdW via IFTTT

An Alternative to Black Holes: Gravastars with Big Bangs Inside

Stellar mass black holes may not be black holes at all. Instead, they could be a type of extremely compact star called a gravastar, which mimics a black hole. This is according to theoretical phsyicists who have discovered a solution to Einstein's Theory of General Relativity that doesn't automatically result in a black hole when a star collapses at the end of its life. from Universe Today https://ift.tt/aQCdprk via IFTTT

Feedback from Young Stars Influences Galaxy Evolution

Star formation is a major driver in galaxy evolution, right up there with the collisions and mergers that shape all galaxies. Researchers led by Ohio State University graduate student Debosmita Pathak, studied 18,000 star-forming regions in nearby spiral galaxies to get a better handle on the influence of starbirth. from Universe Today https://ift.tt/34s0jLr via IFTTT

Europa’s Ice Shell Secrets Unlocked by Ground Radar Study

Jupiter’s moon, Europa, has become high-value real estate for astrobiologists and the search for life beyond Earth. This is because the small moon, which is slightly smaller than Earth’s Moon, boasts a massive subsurface ocean of liquid water that scientists estimate contains about double the amount of water of all Earth’s oceans combined. As seen on Earth, water equals life, so scientists are eager to continue to explore Europa in any way possible to determine if it could harbor life as we know it, or even as we don’t know it. from Universe Today https://ift.tt/CGgOLux via IFTTT

Hubble Spots Two Galaxy Clusters in the Process of Merging

This NASA Hubble Space Telescope image features a galaxy cluster, called CL0016+1609 or MACS J0018.5+1626, that is very bright at X-ray wavelengths and is one of the most extensively studied clusters at X-ray and radio wavelengths. The X-ray observations of this cluster revealed that it is two clusters merging along our line of sight. from Universe Today https://ift.tt/zU78YOC via IFTTT

Scientists Confirm that Two Gamma-Ray Bursts Were Caused by Collapsing Neutron Stars

Listening to the One Place That Swallows Everything

The event horizon of a black hole should be impossible to study. It’s the point of no return, the boundary where gravity grows so strong that not even light can escape, so by definition nothing can carry word of it back to us. Yet a team of scientists have found a way to reach it and found a hidden signal, a faint trace, never read before, carrying information from the very edge of the horizon in the instant before it formed. From it they measured the new black hole's spin and surface gravity, and opened a fresh way to test whether Einstein's theory survives in the most extreme gravity there is. from Universe Today https://ift.tt/uvlYPXd via IFTTT

Hot Jupiter CoRoT-2b Rotates Backward to Orbit

Hot Jupiter exoplanets have completely changed how we look at the universe. This is because before the first exoplanet orbiting a Sun-like star was discovered in 1995, 51 Pegasi b, astronomers theorized every solar system looks just like ours: rocky planets orbiting close to the Sun and gas giants orbiting farther away. In contrast, 51 Pegasi b, whose mass is half of Jupiter and radius is about one-quarter larger, was found to orbit its star in just over 4 days. from Universe Today https://ift.tt/XYaQFjE via IFTTT

Deuterium in Comets Tell Interesting Tales

Comets have play an interesting role in astronomy history. From antiquity, many cultures saw them omens or spirits, portending good or bad news for kings, queens, and emperors. Over the past few hundred years, however, astronomers have studied them intently to understand the science behind these visitors to the inner Solar System. Today we know that these ghostly apparitions in the sky are made of dirty balls of ice and rock blasting through space, scattering dust and gases as they go. from Universe Today https://ift.tt/nQkzWJB via IFTTT

Astronomers Spot a Possible Supernova Remnant Near the Milky Way's Supermassive Black Hole

NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton may have found a supernova remnant near the supermassive black hole at the center of the Milky Way galaxy.

Powerful Solar Storms Can Change Precipitation for Parts of North America

For decades, scientists have searched for a clear link between the Sun’s explosive storms and the weather that occurs on Earth. A breakthrough study from the University of New Hampshire reveals that in the hours and days following a solar storm, parts of North America can see sharp changes in the weather — such as declines in precipitation — and the more powerful the storm, the more dramatic the shift. However, the exact mechanism behind the effects is still waiting for an explanation. from Universe Today https://ift.tt/HLpRvi9 via IFTTT

The Galaxy That Cleared the Fog

For its first billion years the universe was lost in fog, a thick haze of hydrogen that swallowed light whole. Something burned it away, and astronomers have long wondered what. Now Hubble has caught a tiny, furious galaxy in the very act of clearing the murk, glimpsed as it was just 1.4 billion years after the big bang. It may be the smoking gun for how the universe first became clear. from Universe Today https://ift.tt/pyRNEB0 via IFTTT

Crystalline Clocks Confirm Earth's Oldest Crater

A chip of zircon found in Western Australian rocks at a place called North Pole Dome revealed the age of Earth's oldest known impact crater. The team that found it was working on age-dating the crater, which is located in a region called the Pilbara Craton. They used mineral dating to pinpoint the exact time it was dug out by an impactor. Team lead Chris Kirkland from the Timescales of Minerals Systems Group within Curtin University's School of Earth and Planetary Sciences, said the findings help resolve a longstanding question about the timing of the impact. The results of the team's analysis of several minerals at the site, along with zircon, indicated that the North Pole Dome impact occurred at 3.024 billion years ago (plus or minus a few million years). from Universe Today https://ift.tt/zeZLOf5 via IFTTT

Hot Jupiter Endures Star-Powered Barbecue

You’re the grillmaster at the annual family 4th of July BBQ and you’re sweating bullets standing over the grill in the sweltering summer heat. You’re trying to stay cool by pressing a cold beer can on your forehead, but to no avail. You can’t go inside because, once again, you’re the grillmaster and need to watch the food simmering on your freshly cleaned grill. Your brother-in-law is a university astronomy professor and walks over asking how you’re doing. You say, “This heat is killing me.

The Solar Gravitational Lens Could Map White Dwarfs and Black Holes

It feels like every few months we get to report on another academic paper coming out singing the praises of the Solar Gravitational SGL (SGL). Partly, this is due to Dr. Slava Turyshev’s astounding productivity in terms of pumping out academic articles, but partly because such a ground-breaking mission has lots of positive aspects, but also challenges that need to be addressed.

A Quasar at Cosmic Dawn Flickers into View

Astronomers have detected a flickering quasar called J0439+1634 as it appeared only 850 million years after the Big Bang. That discovery raises fresh questions about black hole formation and activity in the early Universe. The flickering light of this distant cosmic lighthouse showed that black hole at the heart of the quasr has a flat, pancake-shaped accretion disk. That shape is more familiar in modern-day quasars, which leads astronomers to wonder how these objects formed so quickly in the infant cosmos? from Universe Today https://ift.tt/4hqInrS via IFTTT

Another Early Universe Surprise from the JWST: A Mature Galaxy Cluster

Are Asteroid-Mass Black Holes Hiding in the Cosmic Gamma-Ray Glow?

There are multiple ways to form black holes. The one most commonly taught in high school physics classes is that they are created from the collapse of a dying star. But there are another class of black holes, known as Primordial Black Holes (PBHs) that could have been created immediately after the Big Bang by matter collapsing in on it. Or that’s the theory at least. Though long theorized, we’ve never actually seen one of them, though scientists have suggested that they might account for the missing mass of the universe, which we otherwise describe as “dark matter”. But a new paper, available in pre-print on arXiv from researchers at Oakland University in Michigan and Rice University in Texas, calls that theory into question, at least for a certain type of PBH. from Universe Today https://ift.tt/T9V7rf0 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.

'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.

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.

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
