Astronomers Find a Black Hole Tipped Over on its Side

Almost every large galaxy has a supermassive black hole churning away at its core. In most cases, these black holes spin in concert with their galaxy, like the central hub of a cosmic wagon wheel. But on December 18, 2024, NASA researchers announced they had discovered a galaxy whose black hole appears to have been turned on its side, spinning out of alignment with its host galaxy. The galaxy, NGC 5084, was discovered centuries ago by German astronomer William Herschel, but it took new t...

Where’s the Most Promising Place to Find Martian Life?

New research suggests that our best hopes for finding existing life on Mars isn’t on the surface, but buried deep within the crust. Several years ago NASA’s Curiosity rover measured traces of methane in the Martian atmosphere at levels several times the background. But a few months later, the methane disappeared, only for it to reappear again later in the year. This discovery opened up the intriguing possibility of life still clinging to existence on Mars, as that could explain the seaso...

Can Entangled Particles Communicate Faster than Light?

Entanglement is perhaps one of the most confusing aspects of quantum mechanics. On its surface, entanglement allows particles to communicate over vast distances instantly, apparently violating the speed of light. But while entangled particles are connected, they don’t necessarily share information between them. In quantum mechanics, a particle isn’t really a particle. Instead of being a hard, solid, precise point, a particle is really a cloud of fuzzy probabilities, with those probabilit...

Building the Black Hole Family Tree

In 2019, astronomers observed an unusual gravitational chirp. Known as GW190521, it was the last scream of gravitational waves as a black hole of 66 solar masses merged with a black hole of 85 solar masses to become a 142 solar mass black hole.

New Research Suggests Io Doesn’t Have a Shallow Ocean of Magma

Jupiter’s moon Io is the most volcanically active body in the Solar System, with roughly 400 active volcanoes regularly ejecting magma into space. This activity arises from Io’s eccentric orbit around Jupiter, which produces incredibly powerful tidal interactions in the interior. In addition to powering Io’s volcanism, this tidal energy is believed to support a global subsurface magma ocean. However, the extent and depth of this ocean remains the subject of debate, with some supporting the idea...

Shielding is the standard way to protect astronauts from radiation during those flights. However, shielding is heavy and, therefore, expensive when it is launched off the Earth. What if, instead, astronauts could hitch a ride on a giant mass of shielding already in space that will take them directly to their destination? That ...

Maybe Venus Was Never Habitable

Although they are very different today, Venus, Earth, and Mars were very similar in their youth. All three were warm, with thick, water-rich atmospheres. But over time, Mars became a cold, dry planet with a thin atmosphere, and Venus became superheated, with a crushing, toxic sky. Only Earth became a warm ocean world teeming with life. But why? We know that Mars once had vast seas. It had the right conditions for life in the beginning, but with less gravity than Earth and a weak magnetic...

Astronauts on Long Missions Will Need Personal AI Assistants

How can artificial intelligence (AI) help astronauts on long-term space missions? This is what a recent study presented at the 2024 International Astronautical Congress in Milan, Italy, hopes to address as an international team of researchers led by the German Aerospace Center introduce enhancements for the Mars Exploration Telemetry-Driven Information System (METIS) system and how this could help future astronauts on Mars mitigate the communications issues between Earth and Mars, which can tak...

Could Primordial Black Holes Be Hiding in Plain Sight?

Are Primordial Black Holes real? They could’ve formed in the unusual physics that dominated the Universe shortly after the Big Bang. The idea dates back to the 1960s, but so far, the lack of evidence makes them purely hypothetical. If they do exist, a new paper suggests they may be hiding in places so unlikely that nobody ever thought to look there. Black holes form when massive stars reach the end of their lives and suffer gravitational collapse. However, Primordial Black Holes (PBHs...

NASA Wants Students’ Help Designing Missions to Other Moons

One of NASA’s primary missions is to inspire the next generation of scientists and engineers to join the STEM field. It does so by producing inspirational and educational content on various platforms. But sometimes, it takes a more direct approach by rewarding students for their contributions to solving a particular problem NASA is facing. Recently, the organization announced such a challenge – the Power to Explore Challenge, which is open to submission from K-12 students until the end of Janua...

Antarctica Has Gotten 10 Times Greener in 35 Years

Our satellites are dispassionate observers of Earth’s climate change. From their vantage point they watch as pack ice slowly loses its hold on polar oceans, ice shelfs break apart, and previously frozen parts of the planet turn green with vegetation. Now, scientists have compiled 35 years of satellite data showing that Antarctica is slowly, yet perceptibly, becoming greener. NASA and the United States Geological Survey sent the first Landsat into space in 1975. Since then, they’ve la...

White Dwarfs Could Have Habitable Planets, Detectable by JWST

In a few billion years, our Sun will die. It will first enter a red giant stage, swelling in size to perhaps the orbit of Earth. Its outer layers will be cast off into space, while its core settles to become a white dwarf. Life on Earth will boil away, and our planet itself might be consumed by the Sun. White dwarfs are the fate of all midsize stars, and given the path of their demise, it seems reasonable to assume that any planets die with their sun. But the fate of white dwarf planets may not...

Catch Jupiter at Opposition 2024 This Coming Weekend

Now is the time to catch Jupiter at its best. The King of the Planets rules the winter night skies. Early December gives sky watchers a good reason to brave the cold, as Jupiter shines at its best. Look for the regal planet rising in the east at sunset, while the Sun sets to the west. Why Opposition? For an outer planet, we call this point ‘opposition’ as the planet sits ‘opposite’ to the Sun from our Earthly perspective. This also means that Jupiter is above the horizon for the en...

Dragonfly is Going to Titan on a Falcon Heavy

NASA has given SpaceX the contract to launch the Dragonfly mission to Saturn’s moon Titan. A Falcon Heavy will send the rotorcraft and its lander on their way to Titan in 2028, if all goes according to plan, and the mission will arrive at Titan in 2034. Dragonfly is an astrobiology mission designed to measure the presence of different chemicals on the frigid moon. Dragonfly will be the second craft to visit Titan, along with the Huygens probe and its short visit back in 2005. Titan i...

A New Reconfigurable Structure Could Be Used to Make Space Habitats

Even some fields that seem fully settled will occasionally have breakthrough ideas that have reverberated impacts on the rest of the fields of science and technology. Mechanics is one of those relatively settled fields – it is primarily understood at the macroscopic level, and relatively few new breakthroughs have occurred in it recently. Until a few years ago, when a group of Harvard engineers developed what they called a totimorphic structure, and a recent paper by researchers at ESA’s Advanc...

What's Inside Uranus and Neptune? A New Way to Find Out

In our search for exoplanets, we’ve found that many of them fall into certain types or categories, such as Hot Jupiters, Super-Earths, and Ice Giants. While we don’t have any examples of the first two in our solar system, we do have two Ice Giants: Uranus and Neptune. They are mid-size gas planets formed in the cold outer regions of the solar system. Because of this, they are rich in water and other volatile compounds, and they are very different from large gas giants such as Jupiter. We still ...

NASA Is Seeking Ideas for Rescuing an Astronaut from the Moon

Space exploration is a dangerous business, especially when squishy living organisms, such as humans, are involved. NASA has always prided itself on how seriously it takes the safety of its astronauts, so as it gears up for the next big push in crewed space exploration, the Artemis program, it is looking for solutions to potentially catastrophic situations that might arise. One such catastrophe would be if one of the Artemis astronauts was incapacitated and couldn’t return to the lander. The onl...

A CubeSat Mission to Phobos Could Map Staging Bases for a Mars Landing

The moons of Mars are garnering increased attention, not only because they could provide a view of the solar system’s past but also because they could provide invaluable staging areas for any future human settlement on Mars itself. However, missions specifically designed to visit Phobos, the bigger of the two moons, have met with varying stages of failure. So why not make an inexpensive mission to do so – one that could launch multiple copies of itself if necessary? That’s the idea behind a Cub...

Interstellar Objects Can't Hide From Vera Rubin

We have studied the skies for centuries, but we have only found two objects known to come from another star system. The first interstellar object to be confirmed was 1I/2017 U1, more commonly known as ?Oumuamua. It was discovered with the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) and stood out because of its large proper motion. Because ?Oumuamua swept through the inner solar system, it was relatively easy to distinguish. The second interstellar object, 2I/Borisov, stood...

The Early Earth Wasn’t Completely Terrible

Earth formed 4.54 billion years ago. The first period of the history of the Earth was known as the Hadean Period which lasted from 4.54 billion to 4 billion years ago. During that time, Earth was thought to be a magma filled, volcanic hellscape. It all sounds rather inhospitable at this stage but even then, liquid oceans of water are thought to have existed under an atmosphere of carbon dioxide and nitrogen. Recent research has shown that this environment may well have been rather more habitabl...
