Could it be aliens? From Cheyava Falls on Mars to exoplanet K2‑18b—here’s what scientists really think

It may seem like we are on the verge of discovering alien life. In 2025, a press release stated that we have the “strongest hints yet” of extraterrestrial life on the exoplanet K2-18b. And when talking about a collected sample from a rock named “Cheyava Falls” on Mars, NASA Administrator Sean Duffy said this was […]

Magnetic field helps binary star systems form, new simulations indicate

New simulations show that interactions with a magnetic field can work to decrease the distance between still forming binary protostars. These results can help explain the characteristics of the binary star systems observed in the Milky Way. The results can also be extrapolated to binary black holes, giving insights into how supermassive black holes evolve. […]

JWST ‘weighs’ dormant black hole 10 billion light-years away

The most distant, nearly invisible dormant black hole has been detected and “weighed” by an international team of astronomers that includes researchers from UCL. The study, published in Science, identified a dormant black hole at the heart of a galaxy known as MRG-M0138 located over 10 billion light years away. It is the most distant […]

Jupiter bow shock reveals electrons accelerating to relativistic speeds

Electrons around Jupiter have been caught in the process of being accelerated, revealing a potentially unified mechanism for particle acceleration. The findings, published in Nature, may help constrain how energetic particles are produced throughout the universe.

Meteors are ‘extremely common.’ What makes the one over New England ‘rare’?

A sonic boom shook Boston and the larger New England area with the force of 230 tons of TNT. The source came from outer space. The Saturday afternoon event triggered shock waves online, with thousands inquiring what could have caused houses to shake and a sound heard as far away as New Hampshire and Rhode […]

Milky Way black hole’s missing wind finally found after a half-century-long search

The hunt is over. After more than 50 years of searching, astrophysicists at Northwestern University have finally discovered evidence of a powerful wind blowing from the Milky Way’s central supermassive black hole, Sagittarius A* (Sgr A*).

Laser ‘origami’ could help astronauts build structures on the moon

University of Florida researchers are exploring how lasers could help astronauts build structures on the moon using materials already available there, including lunar soil transformed into glass. The work, led by Victoria M. Miller, Ph.D., an associate professor in the Herbert Wertheim College of Engineering and researcher with the UF Astraeus Space Institute, recently completed […]

ExoMars rover targets vast bed of clay in search for life

In the region where the ExoMars Rosalind Franklin rover will search for signs of life, clay deposits extend beyond previous estimates, a new study finds. One hypothesis even suggests a vast ocean once covered the landing site.
