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…
FEFU scientists are developing a methodology to calculate the ratio of dust and gas in comas and the tails of comets. This will help us…
GW170817 is the name given to a gravitational wave signal seen by the LIGO and Virgo detectors on August 17, 2017. Lasting for about 100…
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…
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…
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…
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…
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…
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…

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…
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…
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,…
Disc galaxies like our own Milky Way, characterized by a flattened disc of stars and gas (often with a central bulge of material as well)…
The “ghostly particle” is confirmed to have originated from a blazar, nearly 4 billion light years from Earth. For the first time, scientists from around…
The path of light from a star as it passes by a massive body, like an exoplanet, will be bent and an observer looking toward…
