Researchers at the University of Waterloo have been able to capture the first composite image of a dark matter bridge that connects galaxies together. The scientists publish their work in a new paper in Monthly Notices of the Royal Astronomical Society.
A new study pursues a kind of “paleontology” for gravitational waves in an attempt to explain how and why black holes collide and merge.
Astrophysicists at the University of Birmingham have made progress in understanding a key mystery of gravitational-wave astrophysics: how two black holes can come together and merge.
“Titan’s extreme physical environment requires scientists to think differently about what we’ve learned of Earth’s granular dynamics,” said Josef Dufek, with the Georgia Institute of Technology. “Landforms are influenced by forces that aren’t intuitive to us because those forces aren’t so important on Earth. Titan is a strange, electrostatically sticky world.” Visually, Titan is the
Mars’s atmosphere harbours a layer of electrically charged metal atoms, and they’re not behaving as expected.
An Earth-sized planet orbiting a dim star 39 light years away has a hazy atmosphere that could indicate the presence of a “water world”.
The discovery of ZF-COSMOS-20115 is challenging our long-established assumptions about how galaxies form. The “red and dead” galaxy demonstrates just how little we still understand of how the universe began.
In this image from NASA’s Mars Reconnaissance Orbiter, a group of steeply inclined light-toned layers is bounded above and below by unconformities (sudden or irregular changes from one deposit to another) that indicate a “break” where erosion of pre-existing layers was taking place at a higher rate than deposition of new materials.
Mars can blame Jupiter for its small stature. The Red Planet may be much smaller than we expect because Jupiter’s gravity beat it up as it was forming.
NASA will discuss new results about ocean worlds in our solar system from the agency’s Cassini spacecraft and the Hubble Space Telescope during a news briefing 2 p.m. EDT on Thursday, April 13.
