A Machine Learning Algorithm Finds its First Supernova

Plenty of recent mainstream news articles have touted AI’s ability to assist in the process of scientific discovery. But most of them predicted that it could take years or even decades to see the full effect. Astronomy seems ahead of the curve, though, with the announcement of a new AI system developed by researchers at Northwestern University and elsewhere that can now autonomously detect and classify supernovae.

Can We Find the Heaviest Elements in Asteroids?

One of the reasons that asteroid mining is such a popular idea among industrialists is that they holds large quantities of heavy elements. NASA’s Psyche spacecraft just launched this week, headed for an asteroid that holds ten to thirty quintillion U.S dollars worth of rare-earth elements and other heavy metals. During our planet’s formation, the heavier of these elements tended to sink deep into the Earth, making them hard to find. But even in small asteroids, these heavy elements might be much more common and accessible. Since we rely on these rare-earth elements for our modern society, metal-rich asteroids such as Psyche are worth checking out.

Building Roads Out of Moon Dust

Astronauts will face a host of obstacles when they visit the Moon again. There’s powerful radiation, wild temperature swings, and challenging gravity to deal with. There’s also dust and lots of it. Moondust was a hazard for the Apollo astronauts, and future lunar astronauts will have to contend with it, too.

Protostars Can Siphon Material from Far Away

When stars are born, they do it inside a molecular cloud. Astronomers long assumed that the “crèche” supplied all the nutrients that protostars needed to form. However, it turns out they get help from outside the nest.

A Monster Solar Storm Struck Earth 14,300 Years Ago

The Sun is such a stable presence in our lives that we often take it for granted. Few things are as certain sure as the rising of the Sun each morning, and the cycles of the seasons mark the years of our lives. But the Sun is a star, and stars can sometimes be unpredictable. They can emit powerful solar flares and powerful X-rays. With our deep dependence on technology and electricity, the Sun poses a small but real risk to our civilization. As a recent study shows, the Sun has had some extremely powerful flares in recent cosmic times.

Imagine What Life Would be Like on a Giant Rotating Space Station

Inspiration can come in all forms, but one of the best ways to convey ideas and get people excited about them is through art. In particular, video has become one of the most prominent forms of entertainment in our modern lives, whether through 5-second TikToks or 2+ hour-long documentaries on the Crusades. Therefore, it should come as no surprise that some videographers are inspired by concepts in space exploration and can convey that inspiration through their media. And now, thanks to the internet, a new entrant to that category has recently surfaced.

JWST Observes the Kuiper Belt: Sedna, Gonggong, and Quaoar

The Kuiper Belt, the vast region at the edge of our Solar System populated by countless icy objects, is a treasure trove of scientific discoveries. The detection and characterization of Kuiper Belt Objects (KBOs), sometimes referred to as Trans-Neptunian Objects (TNOs), has led to a new understanding of the history of the Solar System. The disposition of KBOs is an indicator of gravitational currents that have shaped the Solar System and reveal a dynamic history of planetary migrations. Since the late 20th century, scientists have been eager to get a closer look at KBOs to learn more about their orbits and composition.

Small Magnetic Fields Have a Big Impact on the Sun's Atmosphere

Surrounding the brilliant Sun is a layer of diffuse plasma known as the corona. You can’t see it most of the time, but if you happen to experience a total eclipse, the corona is the glow that surrounds the shadow of the Moon. The corona is pale white, almost pink because it has a temperature of more than a million Kelvin. This is vastly hotter than the surface of the Sun, which is about 6,500 K. So how does the corona get so hot?

In 250 Million Years, a Single Supercontinent will Form, Wiping Out Nearly all Mammals

A recent study published in Nature Geoscience uses supercomputer climate models to examine how a supercontinent, dubbed Pangea Ultima (also called Pangea Proxima), that will form 250 million years from now will result in extreme temperatures, making this new supercontinent uninhabitable for life, specifically mammals. This study was conducted by an international team of researchers led by the University of Bristol and holds the potential to help scientists better understand how Earth’s climate could change in the distant future from natural processes, as opposed to climate change.

Mercury is Still Shrinking

Mercury is considered a scorching, barren landscape that would literally melt your face off if you were standing on it in full sunlight. But scientists have also known for a long time that it was shrinking…because it was cold. New research based on distinct features in Mercury’s geography suggests that it might continue to do so even today.

NASA's Psyche Mission is off to Asteroid Psyche

On October 13th, at 10:19 AM Eastern (07:19 AM Pacific), NASA’s Psyche mission successfully launched atop a SpaceX Falcon Heavy rocket from Launch Pad 39A at NASA’s Kennedy Space Center in Florida. This spacecraft is now on its way to rendezvous with the M-type asteroid of the same name, an object in the Main Asteroid Belt almost entirely composed of metal. This metallic asteroid is thought to be the remnant of a planetoid that lost its outer layers, leaving behind a core of iron-nickel and precious metals. By studying this object, scientists hope to learn more about the formation of rocky planets.

A Huge New Gaia Data Release: More Stars, Gravitational Lenses and Asteroids

The ESA’s Gaia mission is releasing a new tranche of astronomical data. The mission has released three regular, massive hauls of data since it launched in 2013, named Gaia DR1, DR2, and DR3. The ESA is calling this one a ‘focused product release,’ and while it’s smaller than the previous three releases, it’s still impactful.

The Milky Way’s Stolen Globular Clusters

Modern astronomy holds that all major galaxies (with the Milky Way as no exception) are the accumulation of numerous small mergers. Thus, it should be expected that some of the globular clusters that are now part of our galaxy are likely inherited from other galaxies which have been cannibalized by the Milky Way, or even stolen from intact companion galaxies such as the Magellanic Clouds.

Are Pulsars the Key to Finding Dark Matter?

Ah, dark matter particles, what could you be? The answer still eludes us, and astronomers keep trying new ideas to find them. Such as a new paper in Physical Review Letters that suggests if dark matter is made of axions we might see their remnant glow near pulsars.

A Simulation Predicts Where Astronomers Should Look to Find Intermediate-mass Black Holes

The universe is swimming in black holes, from stellar mass to supermassive behemoths. But, there’s one class that remains elusive: the “middle child” class. These are called “intermediate-mass black holes (IMBH).” How numerous are they, how do they form, and where are they? To answer those questions, astronomers simulated possible formation scenarios.

New Stars Forming Uncomfortably Close to the Milky Way’s Supermassive Black Hole

Astronomers examining a star cluster near Sgr A*, the Milky Way’s supermassive black hole, found that the cluster has some unusually young members for its location. That’s difficult to explain since the region so close to the powerful black hole is infused with powerful radiation and dominated by the black hole’s extremely powerful gravitational force. According to our understanding of stellar formation, young stars shouldn’t be there.

A Comprehensive Blueprint for the Settlement of Mars

Throughout the 20th century, multiple proposals have been made for the crewed exploration of Mars. These include the famed “Mars Project” by Werner von Braun, the “Mars Direct” mission architecture by Robert Zubrin and David Baker, NASA’s Mars Design Reference Mission studies, and SpaceX’s Mars & Beyond plan. By 2033, two space agencies (NASA and the CNSA) plan to commence sending crews and payloads to the Red Planet. These and other space agencies envision building bases there that could eventually lead to permanent settlements and the first “Martians.”
