Jupiter's Lightning Could Be Almost Unbelievably Powerful

March 26, 2026

Juno observations show that Jupiter's lightning, already known to be powerful, is far more energetic than thought. Lightning triggered by a stealth superstorm in 2021-22 could be up to one million times more powerful than terrestrial lightning.

Direct Confirmation Of Two Baby Planets Forming Around A Young Sun-like Star

March 25, 2026

Astronomers have observed two planets forming in the disc around a young star named WISPIT 2. Having previously detected one planet, the team have now employed European Southern Observatory (ESO) telescopes to confirm the presence of another. These observations, and the unique structure of the disc around the star, indicate that the WISPIT 2 system could resemble our young Solar System.

The JWST Finds More Overmassive Black Holes. This Time In Dwarf Galaxies

March 25, 2026

The JWST has shown us that supermassive black holes were much larger in the early Universe than we thought. New research has extended this understanding to more intermediate redshifts, and to dwarf galaxies. Could the often-invoked Super-Eddington accretion be responsible?

Extragalactic Archaeology: A New Method To Understand Galaxy Growth and Evolution

March 24, 2026

Galactic archaeology uses chemical fingerprints in the Milky Way to trace its formation and evolution. Now a team of researchers led by the Center for Astrophysics | Harvard and Smithsonian have employed it for the first time in a distant galaxy. This is the first example of extragalactic archaeology, and it relies on help from the powerful Illustris TNG simulations.

Watching 25 Years of Expansion in the Crab Nebula With the Hubble

March 24, 2026

A quarter-century after its first observations of the full Crab Nebula, NASA’s Hubble Space Telescope has taken a fresh look at the supernova remnant. The result is an unparalleled, detailed look at the aftermath of a supernova and how it has evolved over Hubble’s long lifetime. A paper detailing the new Hubble observation was published in The Astrophysical Journal.

This Ancient Star In A Low-Mass Galaxy Is A Precious Find

March 23, 2026

To understand the Universe we see around us today, we have to understand its past. Some hard-to-find ancient stars, called Population II stars, preserve evidence from the ancient Universe. Astronomers finally found one.

This Pair Of Brown Dwarfs Can't Get Enough Of Each Other

March 20, 2026

Astronomers have found the first case of a brown dwarf binary pair experiencing mass transfer. The pair are very close to one another, with an orbital period of only 57 minutes. The pair will eventually merge into one, brighter star, or the accretor will become massive enough to trigger fusion. At only 1,000 light-years away, the system is a strong candidate for more detailed, follow-up observations.

This Super-Puff Planet is Hiding its True Nature Behind Thick Haze

March 20, 2026

Super-puff planets have extremely low densities, and exoplanet scientists aren't sure why. They seem to defy our understanding of how planets form. Researchers used the JWST to observe the atmosphere of Kepler-51d, one of the puffiest of the super-puffs. Unfortunately, even the powerful space telescope found a featureless spectrum. What does it mean?

The Crab Pulsar's Puzzling Emissions Finally Explained.

March 19, 2026

Pulsars are rapidly rotating neutron stars. The Crab Pulsar, an often studied supernova remnant, is known for its unusual radio emission patterns. New researchs says it's because of a "tug-of-war" between magnetism and gravity. Gravity acts as a focusing lens and plasma in the magnetosphere acts as a defocusing lens.

Sometimes You Get Lucky, Just Like the Hubble Did When It Caught This Comet Disintegrating

March 19, 2026

A team of astronomers were fortunate when their original comet target couldn't be observed with the Hubble. They quickly pivoted to a different target, and caught Comet K1 in the process of breaking apart. This gave them an excellent opportunity to learn more about the doomed object.

A New Type of Exoplanet Has a Magma Ocean That's Lasted 5 Billion Years

March 18, 2026

A study led by the University of Oxford has identified a new type of planet beyond our Solar System – one that stores large amounts of sulphur deep within a permanent ocean of magma. The magma ocean has lasted 5 billion years so far, while Earth's magma ocean likely lasted only tens of millions of years.

Are Rogue Exomoons the Newest Frontier in the Search for Habitability?

March 16, 2026

There may be as many rogue planets or free-floating planets in the Milky Way as there are stars. If there are billions of these worlds, some of them have likely held onto their moons. New research reveals a pathway to habitability for these rogue exomoons.

A Glorious Spiral of Star Formation

March 13, 2026

Stars peek through the dusty, winding arms of NGC 5134, a spiral galaxy located 65 million light-years away, in this Feb. 20, 2026, image from NASA’s James Webb Space Telescope. Webb’s Mid-Infrared Instrument collects the mid-infrared light emitted by the warm dust speckled through the galaxy’s clouds, tracing the clumps and strands of dusty gas. The telescope’s Near Infrared Camera records shorter-wavelength near-infrared light, mostly from the stars and star clusters that dot the galaxy’s spiral arms. The image helps researchers understand star formation in spiral galaxies. Image Credit: ESA/Webb, NASA & CSA, A. Leroy

This Isn't Just Another Rocky World Orbiting a Red Dwarf. This One's Special

March 12, 2026

Rocky planets are found in abundance around M-type stars (red dwarfs), so finding another one doesn't always generate headlines. But an international team of astronomers say that one recent M-dwarf rocky planet found by TESS is especially noteworthy. This one can serve as a benchmark for comparative studies of this type of exoplanet and their at-risk atmospheres.

Only A Supercomputer Can Understand the Extremely Energetic Chaos of a Neutron Star Merger

March 12, 2026

A neutron star merger is an extraordinary event. It features extremely powerful, chaotic magnetic fields that generate extremely energetic photons. Supercomputer simulations show that the extreme gamma-ray photons created in the mayhem can't even escape the chaos.

Finding Gold In A Stellar Explosion

March 11, 2026

NASA telescopes have detected what could be the most distant gamma-ray burst ever detected. A merging pair of neutron stars generated when they merged and exploded as a kilonova. It happened in an unusual location: a tidal stream of debris created by a group of merging galaxies.

Sunday Morning's European Fireball Was Probably Only a Few Meters in Diameter

March 10, 2026

Multiple mobile phones, dashcams, and dedicated meteor cameras capture a fireball over part of Europe on Sunday night. Thousands of people witnessed it, and the ESA's Planetary Defence Team is analyzing it. So far, it looks like it was a few meters in diameter. It lit up the sky, and some debris even struck some buildings in Koblenz, Germany.

The Rubin Observatory's LSST Will Detect Imminent Impactors Before They Crash Into Earth

March 10, 2026

One of the Vera Rubin Observatory's objectives is to detect incoming objects. It's decade-long Legacy Survey of Space and Time will detect one-meter class objects about to impact Earth and allow more detailed observations of them. That will help determine their impact sites with greater accuracy, allowing for more recovery.

The JWST Reveals Some Puzzling Surprises in Jupiter's Northern Aurora

March 09, 2026

Jupiter's powerful, continuous aurorae dwarf those of Earth. Scientists know that Jupiter's Galilean moons created bright spots on Jupiter's northern aurora. The JWST observed these bright spots and generated infrared spectra of them for the first time. Those observations showed that Io's bright spot is extremely variable in both temperature and density, and researchers want to know why.

What Goes On Inside A Massive Star Before It Explodes As A Supernova?

March 04, 2026

When people think of supernova explosions, they're most-often thinking of Type II core-collapse supernovae, where a massive star becomes a red supergiant before collapsing on itself and exploding. New research uncovers what's going on inside the star before it explodes, and explains why SNe light curves can be different from one another.
