A Supermassive Black Hole Just Flipped its Entire Magnetic Field

Black holes are powerful cosmic engines. They provide the energy behind quasars and other active galactic nuclei (AGNs). This is due to the interaction of matter with its powerful gravitational and magnetic fields.

Volcanoes May Have Killed Venus with a Runaway Greenhouse, and Almost the Earth Too

What turned Venus into hell? It could have simply been a steadily-warming Sun, but new research suggests that Volcanoes may have played a role in creating a runaway greenhouse effect. And the same history of active Volcanism almost killed the Earth, too.

This is a Dust Avalanche on Mars

For decades, scientists have observed dark landslides called slope streaks on Mars. First seen by the Viking orbiters in the 1970s, every orbiter mission since has observed them, but the mechanism behind the slope streaks has been hotly debated: could they be caused by water activity on the Red Planet, or are they the result of some sort of dry mechanics?

Traveling the Solar System with Pulsar Navigation

A team of researchers at the University of Illinois Urbana-Champaign have found a way for travelers through the Solar System to work out exactly where they are, without needing help from ground-based observers on Earth. They have refined the pulsar navigation technique, which uses X-ray signals from distant pulsars, in a way similar to how GPS uses signals from a constellation of specialized satellites, to calculate an exact position .

What Does Micrometeoroid Damage do to Gossamer Structures Like Webb’s Sunshield?

Tiny little bullets flood the solar system, each micrometeoroid a potential hazard. New research has found that the James Webb Space Telescope’s thin sunshields, and future inflatable spacecraft, may be at risk.

Lunar Samples Have Been in the Deep Freeze for 50 Years. NASA Finally has the Right Technology to Study Them Properly

Curators handling lunar rocks take extreme care to keep these materials from contamination as they work with them in cold boxes using gloves and protective gear. This frozen Apollo 17 sample is being studied in a nitrogen-purged glove box at NASA Johnson Space Flight Center. Courtesy NASA/Robert Markowitz.

InSight Senses its two Biggest Marsquakes so far, Coming From the Opposite Side of the Planet

On Nov. 26th, 2018, NASA’s Interior Exploration using Seismic Investigations, Geodesy, and Heat Transport (InSight) lander arrived on Mars. Since then, this robotic mission has been using its advanced suite of instruments to study Mars’ interior and geological activity to learn more about its formation and evolution. One of these is the Seismic Experiment for Interior Structure (SEIS), the lander’s primary instrument, which was deployed on the Martian surface less than a month after it arrived.

Why Believing in the Multiverse Isn’t Madness

What is the multiverse? The idea that the universe we inhabit is just one of many parallel universes gets a superhero shout-out in “Doctor Strange in the Multiverse of Madness,” the latest movie based on Marvel comic-book characters.

Scientists Create Molecules that can Follow Darwinian Evolution

A team of researchers at the University of Tokyo have discovered a set of RNA molecules that are capable of replication and diversification. This potentially allows the molecules to undergo Darwinian evolution, pointing the way to a possible first step to life on Earth. As lead author Assistant Professor Ryo Mizuuchi said, “The results could be a clue to solving the ultimate question that human beings have been asking for thousands of years — what are the origins of life?”

Neptune’s Temperature is Behaving Strangely

One of the great things about science is that it builds on itself over time.  Data collected decades ago is still valid and helps scientists spot trends that would otherwise be lost in the flurry of new data they are trying to collect.  And sometimes, that data holds something interesting.  Such is the case when a group of scientists took a look at the infrared data of Neptune’s atmosphere and found not one but two weird changes happening.

The Younger the Planet, the More Likely it is to be Habitable

We’ve discovered thousands of exoplanets and are likely to find many thousands more of them. While the wide variety of planets we’ve found are scientifically interesting in their own right, what lurks behind all these discoveries is the search for a world that could harbour life.

A Magnetic Bubble Could Protect Astronauts From Dangerous Space Radiation

Humans have long dreamed of setting foot on Mars or beyond, and the advances by companies like SpaceX and Blue Origin means perhaps the dream could be closer than ever to becoming reality. But as it stands now, sending astronauts on long-duration missions to other worlds would be impossible because of the hazardous radiation levels in space, outside of Earth’s protective magnetic field.

NASA is Looking for Ideas on How to Simulate Missions to Mars!

In the coming decade, NASA plans to conduct the first crewed missions to Mars. Whereas robotic missions have provided images of the Martian surface for decades, this will be the first time human beings experience the Red Planet directly. In anticipation of these missions, NASA and its commercial partners (Epic Games and Buendea) have come together with HeroX – the leading platform for crowdsourced solutions – to launch the NASA MarsXR Challenge.

NASA Announces the Winners of its Second Payload Challenge!

Lunar exploration has advanced considerably in the last two decades, with more countries sending robotic orbiters, landers, and rovers to the surface than ever before. These missions have taught us much about the Moon’s geological evolution, composition, environment, and resources. In a few years, this information will prove vital as NASA sends the first astronauts to the Moon since the Apollo Era (as part of the Artemis Program). They will be followed by many more crewed missions, which will eventually lead to the creation of lunar bases.

Hydrogen Gas Can Seep Through Rock Providing Food to Bacteria. Another Place to Look for Life On Other Worlds.

Spin Google Earth around until you’re looking down at the nation of Oman. Ancient rock in that country is the backdrop for a new study with consequences for our search for life. Water reacts with this rock to produce hydrogen, which could be an energy source for bacteria. Could this happen on other worlds?

Ingenuity is now Scouting Ahead of Perseverance, Helping it Navigate Difficult Terrain

The Ingenuity Mars Helicopter is providing scientists a look at what is on the road ahead for the Perseverance rover. And acting as a scout, Ingenuity can tell the team what places to avoid, too.

A Space Telescope Could Reveal a Black Hole's Photon Ring

Despite decades of study, black holes remain one of the most powerful and mysterious celestial objects ever studied. Because of the extreme gravitational forces involved, nothing can escape the surface of a black hole (including light). As a result, the study of these objects has traditionally been confined to observing their influence on objects and spacetime in their vicinity. It was not until 2019 that the first image of a black hole was captured by the Event Horizon Telescope (EHT).
