Researchers using NASA's Mars Reconnaissance Orbiter (MRO) have found eight sites where thick deposits of ice beneath Mars' surface are exposed in faces of eroding slopes.
These eight scarps, with slopes as steep as 55 degrees, reveal new information about...
Astronomers have caught a supermassive black hole in a distant galaxy snacking on gas and then "burping" -- not once, but twice.
The galaxy under study, called SDSS J1354+1327 (J1354 for short), is about 800 million light-years from Earth. The...
Astronomers using the Green Bank Telescope have made the first definitive interstellar detection of benzonitrile, an intriguing organic molecule that helps to chemically link simple carbon-based molecules and truly massive ones known as polycyclic aromatic hydrocarbons. This discovery is...
Two wayward space rocks, which separately crashed to Earth in 1998 after circulating in our solar system's asteroid belt for billions of years, share something else in common: the ingredients for life. They are the first meteorites found to...
Astronomers have looked back to a time soon after the Big Bang, and have discovered swirling gas in some of the earliest galaxies to have formed in the Universe. These 'newborns' - observed as they appeared nearly 13 billion...
New detections of radio waves from a repeating fast radio burst have revealed an astonishingly potent magnetic field in the source's environment, indicating that it is situated near a massive black hole or within a nebula of unprecedented power.
The...
Through first-of-their-kind supercomputer simulations, researchers, including a Northwestern University professor, have gained new insight into one of the most mysterious phenomena in modern astronomy: the behavior of relativistic jets that shoot from black holes, extending outward across millions of...
Scientists have solved a cosmic mystery by finding evidence that supermassive black holes prevent stars forming in some smaller galaxies.
These giant black holes are over a million times more massive than the sun and sit in the centre of...
An international research team led by Université de Montréal astrophysicist Lauren Weiss has discovered that exoplanets orbiting the same star tend to have similar sizes and a regular orbital spacing. This pattern, revealed by new W. M. Keck Observatory...
Using the now-complete Cassini data set, Cornell astronomers have created a new global topographic map of Saturn's moon Titan that has opened new windows into understanding its liquid flows and terrain. Two new papers, published Dec. 2 in Geophysical...
An international team of astronomers has revealed an 'astonishing' overabundance of massive stars in a neighbouring galaxy.
The discovery, made in the gigantic star-forming region 30 Doradus in the Large Magellanic Cloud galaxy, has 'far-reaching' consequences for our understanding of...
