Monster Galaxies Gain Size by Consuming Smaller Neighbors

A newly published study examined galaxy growth, revealing that massive galaxies are much less efficient at star formation than smaller galaxies and instead grew by merging other galaxies. Massive galaxies in the Universe have stopped making their own stars and are instead snacking on nearby galaxies, according to research by Australian scientists. Astronomers looked at […]

Chandra Discovers Planet That Makes Star Act Deceptively Old

A new study from NASA’s Chandra X-ray Observatory shows that a giant exoplanet, WASP-18b, is making the star that it orbits act much older than it actually is. WASP-18b is over ten times Jupiter’s mass and is so close to its star that it completes an orbit in less than a day, causing extreme tidal […]

Meteorite Reveals the Possibility of Life on Mars

An unusual feature embedded deep within a fragment of a Martian meteorite is helping to make the case for the possibility of life on Mars. The finding of a ‘cell-like’ structure, which investigators now know once held water, came about as a result of collaboration between scientists in the UK and Greece. Their findings are […]
