The first known Jupiter Trojan asteroid to have sprouted a comet-like...

Asteroids and comets are often thought of as distinct types of small bodies, but astronomers have discovered an increasing number of “crossovers.” These objects...

Hubble Sees Stellar Glitter in a Cosmic Void

Unlike a spiral or elliptical galaxy, the galaxy KK 246 looks like glitter spilled across a black velvet sheet. KK 246, also known as...

ALMA found quasi-periodic flickers in millimeter-waves from the center of the...

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) found quasi-periodic flickers in millimeter-waves from the center of the Milky Way, Sagittarius (Sgr) A*. The...

A neutron star binary this massive has never been seen in...

Earlier this year, an international team of scientists announced the second detection of a gravitational-wave signal from the collision of two neutron stars. The...

ALMA Discovers Massive Rotating Disk in Early Universe

In our 13.8 billion-year-old universe, most galaxies like our Milky Way form gradually, reaching their large mass relatively late. But a new discovery made...

ESO telescope have revealed the telltale signs of a star system...

Observations made with the European Southern Observatory’s Very Large Telescope (ESO’s VLT) have revealed the telltale signs of a star system being born. Around...

Ultra-thin sail could speed journey to other star systems

A tiny sail made of the thinnest material known – one carbon-atom-thick graphene – has passed initial tests designed to show that it could...

New Study Estimates the Odds of Life and Intelligence Emerging Beyond...

Humans have been wondering whether we are alone in the universe since antiquity. We know from the geological record that life started relatively quickly, as...

First Independent Confirmation of PDS 70 Protoplanets

New evidence shows the first-ever pictures capturing the birth of a pair of planets orbiting the star PDS 70 are in fact authentic. Using a...

New fermi catalog adds 2000 gamma-ray sources

The Fermi-LAT collaboration has published its fourth source catalog, named 4FGL. Based on eight years of data, it contains 5064 celestial objects emitting gamma...

Studies predict 100 more undiscovered galaxies are out there orbiting the...

We live in a big-city galaxy. The Milky Way is so big it has satellite galaxies that orbit it, just as the Moon orbits...

Mergers between black holes and neutron stars in dense star clusters

Mergers between black holes and neutron stars in dense star clusters are quite unlike those that form in isolated regions where stars are few....

NASA’s TESS Enables Breakthrough Study of Perplexing Stellar Pulsations

Astronomers have detected elusive pulsation patterns in dozens of young, rapidly rotating stars thanks to data from NASA’s Transiting Exoplanet Survey Satellite (TESS). The...

Powerful new AI technique detects and classifies objects in astronomical images

Researchers at UC Santa Cruz have developed a powerful new computer program called Morpheus that can analyze astronomical image data pixel by pixel to...

New insights into exploding massive stars and the next generation of...

In a study recently published in the Monthly Notices of the Royal Astronomical Society, researchers Dr Jade Powell and Dr Bernhard Mueller from the...

Astronomers discovered a black hole lying just 1000 light-years from Earth

A team of astronomers from the European Southern Observatory (ESO) and other institutes has discovered a black hole lying just 1000 light-years from Earth....

The next-generation telescopes might look first for hydrogen atmospheres

As new and more powerful telescopes blink on in the next few years, astronomers will be able to aim the megascopes at nearby exoplanets,...

NASA analyze the atmosphere of Super-Hot Planet WASP-79b

The weather forecast for the giant, super-hot, Jupiter-size planet WASP-79b is steamy humidity, scattered clouds, iron rain and yellow skies. NASA's Hubble Space Telescope teamed...

NASA James Telescope Unravel Riddles of a Stellar Nursery

A bustling stellar nursery in the picturesque Orion Nebula will be a subject of study for NASA’s James Webb Space Telescope, scheduled to launch...

Astronomers captured images of the inner rims of planet-forming disks around...

An international team of astronomers has captured fifteen images of the inner rims of planet-forming disks located hundreds of light years away. These disks...

Newly discovered exoplanet three times the mass of Jupiter called Kepler-88-d

Our solar system has a king. The planet Jupiter, named for the most powerful god in the Greek pantheon, has bossed around the other...

The largest black holes ever found, with over 18 billion times...

Black holes aren't stationary in space; in fact, they can be quite active in their movements. But because they are completely dark and can't...

For the first time researchers model a superluminous supernova system in...

For most of the 20th century, astronomers have scoured the skies for supernovae—the explosive deaths of massive stars—and their remnants in search of clues...

The ultraviolet light emitted by the star formation in very massive...

The sparsely distributed hot gas found today between galaxies, the intergalactic medium (IGM), is ionized. The early universe started off hot, but then it...

Common Envelope Shaping of Planetary Nebulae and Magnetic Solutions

Magnetic fields of order 101–102 Gauss that are present in the envelopes of red giant stars are ejected in common envelope scenarios. These fields could...

First-ever photographic proof of power-packed jet emerging from colliding galaxies

A team of Clemson University College of Science researchers, in collaboration with international colleagues, has reported the first definitive detection of a relativistic jet...

Tomanowos: The meteorite that survived mega-floods and human folly

The rock with arguably the most fascinating story on Earth has an ancient name: Tomanowos. It means “the visitor from heaven” in the extinct...

An Eclipsing Binary Millisecond Pulsar Discovered by FAST

Using the data obtained by the Five-hundred-meter Aperture Spherical radio Telescope (FAST), a research team led by Prof. PAN Zhichen and Prof. LI Di...
