Scientists have uncovered the first robust evidence of a black hole and neutron star crashing together but orbiting in an oval path rather than a perfect circle just before they merged. This discovery challenges long-standing assumptions about how these cosmic pairs form and evolve.

Lunar dust can be a pain—but it’s also literally the ground we will have to traverse if we are ever to have a permanent human settlement on the moon. In that specific use case, its clingy, jagged, staticky properties can actually be an advantage, according to a new paper recently published in Research from scientists […]
A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an environment like this before—and it may help solve two outstanding cosmic mysteries. A paper describing these results is forthcoming […]
We all know that stars radiate light and much more. But radiation belts can also surround many other celestial bodies, such as planets. These belts do not generate particles themselves—the belts receive them from nearby stars—but they accelerate the speed of particles in a way that has remained elusive.

Billions of light years away in a remote part of the universe, two neutron stars—the ultradense remnants of dead stars—collided. The catastrophic cosmic event sent light and particles, including a sudden flash of gamma rays, streaming through the universe. These gamma rays traveled for 8.5 billion years before reaching Earth.

Up until now, exoplanet surveys have mostly focused on nearby, bright stars that are sun-like or are red dwarfs, which are known to frequently host planets. While astronomers have discovered thousands of planets this way, a new study, published in the Monthly Notices of the Royal Astronomical Society, seems to have found a more efficient […]
The European Space Agency said it is investigating a fireball that streaked across the skies of Europe on the weekend before reportedly punching a football-sized hole in the roof of a German home.

NASA’s Van Allen Probe A is expected to reenter Earth’s atmosphere almost 14 years after launch. From 2012 to 2019, the spacecraft and its twin, Van Allen Probe B, flew through the Van Allen belts, rings of charged particles trapped by Earth’s magnetic field, to understand how particles were gained and lost. The belts shield […]
A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an international team of astronomers led by Penn State scientists. The burst, known as GRB 230906A, was likely caused by the collision of two neutron stars hundreds of millions of years ago and is now shedding light […]
Observations of the Rimae Bode region on the moon reveal five distinct types of terrain and identify several potential landing sites for China’s first crewed mission, according to research titled “Geology of Rimae Bode region as priority site candidate for China’s first crewed lunar mission.” The work is published in Nature Astronomy.

Asteroids are some of the oldest objects in the solar system: leftovers from the chaotic time when planets were assembling from dust and rock. They’re time capsules, preserving clues about what the early solar system was like, and, ultimately, what the building blocks of planets are.

Even when the idea of terraforming Mars was originally put forward, the idea was daunting. Changing the environment of an entire planet is not something to do easily. Over the following decades, plenty of scientists and engineers have looked at the problem, and most have come to the same conclusion—we’re not going to be able […]
In 2020, a study confirmed that two planets orbited the nearby red dwarf, GJ 887. Now, astronomers have confirmed the existence of two additional planets orbiting GJ 887 in a new study published in Astronomy and Astrophysics. The new study suggests that one of these newly confirmed planets is in the habitable zone.

Three years ago, in the waters of the Mediterranean Sea, the passage of an “ultra-energetic” cosmic neutrino was observed—the most energetic ever detected. The event drew international attention from the scientific community as well as from the media and the public, not least because the origin of this particle—whose energy exceeded that of previously observed […]
By analyzing the data from various space observatories and ground-based telescopes, European astronomers have performed a multiwavelength study of a bright gamma-ray blazar known as S5 1044+71. The new study, published Feb. 26 on the arXiv pre-print server, delivers a comprehensive view of this blazar, which could help us better understand its nature.
