Chandra Reveals Critical Evidence of Elusive Intermediate-Mass Black Holes
Scientists have taken major steps in their hunt to find black holes that are neither very small nor extremely large. Finding these elusive intermediate-mass black…
Astronomers Show How Colliding Galaxies May Seed Future Stars
A pair of dwarf galaxies closely circling the Milky Way, the Large and Small Magellanic Clouds, were in the throes of merging into one when…
Astronomers Use the Umov Effect to Unravel the Mysteries of the Universe
FEFU scientists are developing a methodology to calculate the ratio of dust and gas in comas and tails of comets. This will help learn more…
Spitzer Observations of Binary Neutron Star Merger GW170817
GW170817 is the name given to a gravitational wave signal seen by the LIGO and Virgo detectors on 17 August 2017. Lasting for about 100…
Fastest Jettisoned Gas Ever Measured from a Stellar Outburst
Observations from the Gemini South and other telescopes in Chile played a critical role in understanding light echoes from a stellar eruption which occurred almost…
Ancient Blue Crystals Reveal What the Early Sun Was Like
Our Sun’s beginnings are a mystery. It burst into being 4.6 billion years ago, about 50 million years before the Earth formed. Since the Sun…
Colliding Stars Spill Radioactive Molecules In Interstellar Space
Astronomers have made the first definitive detection of a radioactive molecule in interstellar space: a form, or isotopologue of aluminum monofluoride (26AlF). The new data – made…
Like a Huge Spiral, the Milky Way Floats in Space
For thousands of years, people have been puzzling over the milky strip that extends across the entire firmament. In the modern era, Galileo Galilei discovered…
Astronomers Study Enduring ‘Radio Rebound’ from Gamma-Ray Burst 161219B
In the blink of an eye, a massive star more than 2 billion light-years away lost a million-year-long fight against gravity and collapsed, triggering a…
Further Evidence That Outskirts of Spiral Galaxies Host Massive Black Holes
Findings from a Rochester Institute of Technology study provide further evidence that the outskirts of spiral galaxies host massive black holes. These overlooked regions are…
Astronomers Conduct Successful Test of Einstein Theory Near a Supermassive Black Hole
Astronomers conduct successful test of Einstein’s general theory of relativity near supermassive black hole. The massive black hole at the heart of the Milky Way…
Scientists Create Metallic Hydrogen to Unravel the Mysteries of the Dynamo Effect
Metallic hydrogen is one of the rarest materials on Earth, yet more than 80 percent of planets—including Jupiter, Saturn, and hundreds of extrasolar planets—are composed…
Astronomers Discover New Way to Unlock the Mysteries of the First Galaxies
A team of astronomers has discovered a new way to unlock the mysteries of how the first galaxies formed and evolved. In a study published…
NASA’s MAVEN Spacecraft Just Found a New Type of Martian Aurora
Auroras appear on Earth as ghostly displays of colorful light in the night sky, usually near the poles. Our rocky neighbor Mars has auroras too,…
Astronomers Reveal Unified Model for Galactic Discs: Star Formation, Turbulence Driving, and Mass Transport
