Did life really exist on Mars after all? Unfortunately, there is no conclusive evidence for this yet. Nevertheless, it would seem that some form of life was the driving force behind the mysterious Martian dune […]

White dwarfs are the compact remnants of stars that have stopped nuclear burning, a fate that will eventually befall our sun. These extremely dense objects are degenerate stars because their structure is counterintuitive: the heavier […]

A pair of Sydney Ph.D. students helped sharpen the view of humanity’s most powerful space observatory—without leaving Earth. As an indelible reminder of this thrilling result, Louis Desdoigts, now a postdoctoral researcher at Leiden in […]

Scientists at MIT and elsewhere have discovered extremely rare remnants of “proto Earth,” which formed about 4.5 billion years ago, before a colossal collision irreversibly altered the primitive planet’s composition and produced Earth as we […]

Any life on Mars in the past, present, or future would have to contend with challenging conditions including, among others, shock waves from meteorite impacts and soil perchlorates—highly oxidizing salts that destabilize hydrogen bonds and […]

SpaceX launched another of its mammoth Starship rockets on a test flight Monday, successfully making it halfway around the world while releasing mock satellites like last time.This post was originally published on this site

Dark matter, the substance that makes up about 27% of the universe, could potentially be detected as a red or blue light “fingerprint,” new research shows. The research is published in the journal Physics Letters […]

Using 11 years of magnetic field measurements from the European Space Agency’s Swarm satellite constellation, scientists have discovered that the weak region in Earth’s magnetic field over the South Atlantic—known as the South Atlantic Anomaly—has […]

New research has found that amino acids, the building blocks of life, may have traveled to Earth on interstellar dust grains, potentially helping kickstart biology as we know it.This post was originally published on this […]

Using various space telescopes, an international team of astronomers have observed a newly detected very faint X-ray transient designated 4XMM J174610.7–290020. Results of the observational campaign, published October 2 on the arXiv pre-print server, yield […]
