Hubble determines mass of isolated black hole roaming our Milky Way galaxy

The Hubble Space Telescope has, for the first time ever, provided direct evidence for a lone black hole drifting through interstellar space by a precise mass measurement of the phantom object.

Researchers find ten billion-year old 'ghost stars' from swallowed galaxy

Astronomers have found a group of stars in the Milky Way disk, that are most likely remnants from an unknown baby galaxy that was swallowed by the Milky Way over 10 billion years ago. Nothing like it has been discovered in the galaxy disk before.

Ground-breaking number of brown dwarfs discovered

Brown dwarfs are mysterious astronomical objects that fill the gap between the heaviest planets and the lightest stars, with a mix of stellar and planetary characteristics. Due to this hybrid nature, these puzzling objects are crucial to improve our understanding of both stars and giant planets.

Rapid-fire fast radio burst shows hot space between galaxies

A recently discovered, rare and persistent rapid-fire fast radio burst source - sending out an occasional and informative cosmic ping from more than 3.5 billion light years away - helps to reveal the secrets of the broiling hot space between the galaxies.

Strange radio burst raises new questions

Astronomers have found only the second example of a highly active, repeating Fast Radio Burst (FRB) with a compact source of weaker but persistent radio emission between bursts. The discovery raises new questions about the nature of these mysterious objects and also about their usefulness as tools for studying the nature of intergalactic space.

Detecting new particles around black holes with gravitational waves

Clouds of ultralight particles can form around rotating black holes. A team of physicists now show that these clouds would leave a characteristic imprint on the gravitational waves emitted by binary black holes.

'Dust echo' reveals cosmic catastrophe

In a distant galaxy in the constellation Hercules, a gigantic black hole has torn apart a giant star. This is shown by extensive observations with several observatories.

Astronomers find evidence of galactic metal shrouded in dust

Scientists uncovered evidence of heavier elements in local galaxies - found to be deficient in earlier studies - by analyzing infrared data gathered during a multiyear campaign.

New observations help explain why Uranus and Neptune are different colors

Astronomers have developed a single atmospheric model that matches observations of both planets. The model reveals that excess haze on Uranus builds up in the planet's stagnant, sluggish atmosphere and makes it appear a lighter tone than Neptune.

Supermassive black holes inside of dying galaxies detected in early universe

The appearance of these active supermassive black holes correlates with changes in the host galaxy, suggesting that a black hole could have far reaching effects on the evolution of its host galaxy.

Why haven't we discovered co-orbital exoplanets? Could tides offer a possible answer?

So far, we haven't discovered any exoplanets with co-orbital objects. A new study suggests tides could be causing oscillations that remove co-orbitals before we can find them.

New discovery about distant galaxies: Stars are heavier than we thought

A team of astrophysicists has arrived at a major result regarding star populations beyond the Milky Way. The result could change our understanding of a wide range of astronomical phenomena, including the formation of black holes, supernovae and why galaxies die.
