Curiosity Weather Data Bolsters Case for Brine

New calculations indicate favorable conditions for small quantities of brine to form during some nights throughout the year on Mars. The possibility for liquid brines on Mars has wider implications for habitability and geological water-related processes. Martian weather and soil conditions that NASA’s Curiosity rover has measured, together with a type of salt found in […]

NASA is Finding Water in Surprising Places

As NASA scientists explore our solar system and search for new worlds, they are finding water in surprising places. Water is but one piece of our search for habitable planets and life beyond Earth, yet it links many seemingly unrelated worlds in surprising ways. “NASA science activities have provided a wave of amazing findings related […]

New Hubble Image of Globular Cluster Messier 22

This newly released Hubble image shows the center of the globular cluster Messier 22, also known as M22. Globular clusters are spherical collections of densely packed stars, relics of the early years of the Universe, with ages of typically 12 to 13 billion years. This is very old considering that the Universe is only 13.8 […]

Hubble Reveals Phantom Objects Near Dead Stars

Astronomers have identified eight galaxies with bright active nuclei that have illuminated material far outside the radius of the galaxy. The eerie structures have looping, spiral, and braided shapes. Hubble’s images show that they are like the remnants of galaxy collisions. NASA’s Hubble Space Telescope has photographed a set of wispy, goblin-green objects that are […]

Astronomers Identified Some of the Oldest and Rarest Galaxy Clusters

By using data from ESA’s Herschel and Planck space observatories, astronomers have discovered what could be the precursors of the vast clusters of galaxies that we see today. One telescope finds the treasure chest, and the other narrows in on the gold coins. Data from two European Space Telescope missions, Planck and Herschel, have together […]

G2 Passes Supermassive Black Hole

New VLT observations confirm that the dusty gas cloud G2 made its closest approach to the supermassive black hole at the center of the Milky Way in May 2014 and has survived the experience. The new result from ESO’s Very Large Telescope shows that the object appears not to have been significantly stretched and that […]

Astronomers Find Clues that May Help Identify Dark Matter

In a newly published study, astronomers used X-rays from Chandra and optical data from Hubble to help narrow down the possibilities of what dark matter can be and to set new limits on how dark matter interacts with itself. Using observations from NASA’s Hubble Space Telescope and Chandra X-ray Observatory, astronomers have found that dark […]

Astronomers Link Black-Hole Wind to a Galactic Gush of Star-Forming Gas

A newly published study is the first to directly connect a galaxy’s actively ‘feeding’ black hole to features found at much larger physical scales, revealing that it’s responsible for blowing star-forming gas out of the galaxy’s central regions. By combining observations from the Japan-led Suzaku X-ray satellite and the European Space Agency’s infrared Herschel Space […]

NASA Views Growth Spurt from Newborn Protostar

Satellite and ground-based data has revealed an outburst from HOPS 383. This is the first outburst astronomers have ever seen from a Class 0 object, and it appears to be the youngest protostellar eruption ever recorded. Using data from orbiting observatories, including NASA’s Spitzer Space Telescope, and ground-based facilities, an international team of astronomers has […]

Researchers Discover the Sound of Stars

A chance discovery by a team of physicists has provided experimental evidence that stars may generate sound. The study of fluids in motion – now known as hydrodynamics – goes back to the Egyptians, so it is not often that new discoveries are made. However when examining the interaction of an ultra-intense laser with a […]

Carnufex Carolinensis

New research from North Carolina State University shows that a 9-foot long crocodile ancestor may have been North America’s top predator before the dinosaurs arrived. A newly discovered crocodilian ancestor may have filled one of North America’s top predator roles before dinosaurs arrived on the continent. Carnufex carolinensis, or the “Carolina Butcher,” was a 9-foot […]
