Observations of large valley networks on today’s Mars suggest formation by flowing water. However, most climate models cannot sustain temperatures above freezing. To understand this contradiction, a ...

The fossil record of freshwater crayfish is surprisingly sparse, comprising mostly trace fossils, some body fossils and rarely gastroliths. Paleontologists from Flinders University, the University of ...

Certain lichen species can withstand Mars-like conditions with an X-ray radiation dose of 50 Gy (Grays) that is expected on the Mars surface over one year of strong solar activity, according to new ...

Light from an extremely distant spiral galaxy was bent and magnified by the gravity of a member of the galaxy cluster SMACSJ0028.2-7537 into a ring-like structure, called an Einstein ring. Einstein ...

Paleontologists have examined teeth of Teleoceras major — an extinct species of rhinocerotid that lived in North America from 17.5 to 5 million years ago — found at the Ashfall Fossil Beds in Nebraska ...

Using Lawrence Berkeley National Laboratory’s 88-Inch Cyclotron, an international team of physicists has successfully made two atoms of livermorium (atomic symbol Lv) using a titanium beam for the ...

The newly-discovered shape-recovering liquids defy long-held expectations derived from the laws of thermodynamics, according to a team of physicists at the University of Massachusetts Amherst.

Astronomers using the MUSE instrument at ESO’s Very Large Telescope (VLT) have detected supermassive black hole-driven winds in the barred spiral galaxy NGC 4945. NGC 4945 resides over 12 million ...

Colossal Biosciences, the world’s only de-extinction company, has announced the rebirth of the once extinct dire wolf (Aenocyon dirus). Dire wolves were large wolf-like canids and among the most ...

A new study by University of California, San Diego computational astrophysicist Ethan Nadler shows that star formation can occur in halos down to 10 million solar masses through molecular hydrogen ...

“Planetary nebulae are the spectacular final display at the end of a giant star’s life,” Hubble astronomers said in a statement. “Once a red giant star has exhausted its available fuel and shed its ...
