The first evidence of a giant planet orbiting a dead white dwarf star has been found in the form of a disc of gas formed from its ... read more
An astrophysicist has discovered many new multiple star systems that contain exoplanets. For this, he searched more than 1,300 exoplanet host stars. He found that 15 per cent ... read more

A Runaway Star Ejected from the Galactic Heart of Darkness

Astronomers have spotted an ultrafast star, traveling at a blistering 6 million km/h, that was ejected by the supermassive black hole at the heart at the Milky Way five million years ago. The ... read more

Scientists May Have Discovered Whole New Class of Black Holes

New research shows that astronomers' search for black holes might have been missing an entire class of black holes that they didn't know existed. Astronomers offer a new way to search for black ... read more

Conditions That Trigger Supernovae Explosions

For the first time, researchers were able to demonstrate the process of detonation formation using both experiments and numerical simulations carried out on ... read more

Worldwide Observations Confirm Nearby 'Lensing' Exoplanet

Researchers using telescopes around the world confirmed and characterized an exoplanet orbiting a nearby star through a rare phenomenon known as gravitational microlensing. The exoplanet has a mass ... read more

Even 'Goldilocks' Exoplanets Need a Well-Behaved Star

Scientists model how the 'weather' on a star impacts exoplanets to see if even those thought to be in habitable zones could suffer from solar storms. They expect their work to help narrow ... read more

Simulations Explain Giant Exoplanets With Eccentric, Close-in Orbits

As planetary systems evolve, gravitational interactions between planets can fling some of them into eccentric elliptical orbits around the host star. Smaller planets should be more susceptible to ... read more

How to Spot a Wormhole (If They Exist)

Whether wormholes exist is up for debate. But in a recent article, physicists describe a technique for detecting these ... read more

First Identification of a Heavy Element Born from Neutron Star Collision

For the first time, a freshly made heavy element, strontium, has been detected in space, in the aftermath of a merger of two neutron stars. The detection confirms that the heavier elements in the ... read more

Mix Master: Modeling Magnetic Reconnection in Partially Ionized Plasma

Many of the most dramatic events in the solar system -- the spectacle of the Northern Lights, the explosiveness of solar flares, and the destructive impact of geomagnetic storms that can disrupt ... read more

A Star Is Born: Using Lasers to Study How Star Stuff Is Made

On a typical day at the world's biggest laser you can find scientists casually making star-like conditions using 192 high-powered lasers. Stars in the universe are formed through a process ... read more

Gravity Crystals: A New Method for Exploring the Physics of White Dwarf Stars

Grab a mixing bowl from your kitchen, throw in a handful of aluminum balls, apply some high voltage, and watch an elegant dance unfold where particles re-arrange themselves into a distinct ... read more

Earth-like planets may be common in the universe, a new study implies. The team of astrophysicists and geochemists presents new evidence that the Earth is not ... read more

Hubble has given astronomers their best look yet at an interstellar visitor -- comet 2I/Borisov -- whose speed and trajectory indicate it has come from beyond our solar system. Comet 2I/Borisov is ... read more

For the first time, astronomers have witnessed 3D motions of gas in a planet-forming disk. At three locations in the disk around a young star called HD 163296, gas is flowing like a waterfall into ... read more

Heron Survey Fishes out Detail in Ghostly Galaxy Outskirts

Astronomers have completed the largest survey to date of the faint outskirts of nearby galaxies, successfully testing a low-cost system for exploring these local stellar systems. The team find that ... read more

Astronomers Use Giant Galaxy Cluster as X-Ray Magnifying Lens

Astronomers have used a massive cluster of galaxies as an X-ray magnifying glass to peer back in time, to nearly 9.4 billion years ago. In the process, they spotted a tiny dwarf galaxy in its very ... read more

Astronomers have discovered that powerful winds driven by supermassive black holes in the centers of dwarf galaxies have a significant impact on the evolution of these galaxies by suppressing star ... read more

The Milky Way Kidnapped Several Tiny Galaxies from Its Neighbor

A team of astronomers has discovered that several of the small -- or 'dwarf' -- galaxies orbiting the Milky Way were likely stolen from the Large Magellanic Cloud, including several ... read more

How Do the Strongest Magnets in the Universe Form?

How do some neutron stars become the strongest magnets in the Universe? Astrophysicists have found a possible answer to the question of how these so-called magnetars form. Researchers have used large ... read more

Liquifying a Rocky Exoplanet

A hot, molten Earth would be around 5% larger than its solid counterpart. The difference between molten and solid rocky planets is important for the search of Earth-like worlds beyond our Solar ... read more

Massive Filaments Fuel the Growth of Galaxies and Supermassive Black Holes

Based on direct observations researchers have discovered massive filaments between galaxies in a proto-cluster, extending over more than 1 million parsecs and providing the fuel for intense formation ... read more
