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

Monstrous Galaxy from Dawn of the Universe Accidentally Discovered

The early universe is filled with monsters, a new study revealed. Researchers discovered a previously invisible galaxy, and perhaps a new galaxy population waiting to be ... 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

Making Connections: Bringing Astrophysical Processes Down to Earth

Magnetic reconnection, a process in which magnetic field lines tear and come back together, releasing large amounts of kinetic energy, occurs throughout the universe. The process gives rise to ... 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

New Understanding of the Evolution of Cosmic Electromagnetic Fields

Electromagnetism was discovered 200 years ago, but the origin of the very large electromagnetic fields in the universe is still a ... read more

Going Against the Flow Around a Supermassive Black Hole

At the center of a galaxy called NGC 1068, a supermassive black hole hides within a thick doughnut-shaped cloud of dust and gas. When astronomers used the Atacama Large Millimeter/submillimeter Array ... 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

Milky Way Raids Intergalactic 'Bank Accounts'

Gas blown out of the Milky Way disk from exploding stars falls back onto the galaxy to form new generations of stars. In an effort to account for this recycling process, astronomers were surprised to ... 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

2019 Nobel Prize in Physics: Evolution of the Universe and Discovery of Exoplanet Orbiting Solar-Type Star

This year's Nobel Prize in Physics is being awarded "for contributions to our understanding of the evolution of the universe and Earth's place in the cosmos," with one half to ... 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

This Is How a 'Fuzzy' Universe May Have Looked

Scientists have found that the early universe, and the very first galaxies, would have looked very different depending on the nature of dark matter. For the first time, the team has simulated what ... read more

The Violent History of the Big Galaxy Next Door

Astronomers have pieced together the cannibalistic past of our neighboring large galaxy Andromeda, which has now set its sights on the Milky Way as its next main ... read more

Quantum Vacuum: Less Than Zero Energy

According to quantum physics, energy can be 'borrowed' -- at least for some time. Energies lower than zero are possible, much like a bank account that can be overdrawn. There are, however, ... read more

Oldest Galaxy Protocluster Forms 'Queen's Court'

Astronomers have discovered a collection of 12 galaxies which existed about 13.0 billion years ago. One of the 12 galaxies is a giant object, known as Himiko, which was named for a mythological queen ... read more

Artificial Intelligence Probes Dark Matter in the Universe

Physicists and computer scientists have developed a new approach to the problem of dark matter and dark energy in the universe. Using machine learning tools, they programmed computers to teach ... read more
