Highly energetic and difficult to detect, neutrinos travel billions of light years before reaching our planet. Although it is known that these elementary particles come from the depths of our Universe, their precise origin is still unknown. Researchers are now shedding light on one aspect of this mystery: neutrinos are thought to be born in blazars, galactic nuclei fed by supermassive black holes.

Astronomers have discovered a mysterious short-duration astronomical event that was as bright as a superluminous supernova, but evolving much faster.

New COMAP radio survey will peer beneath the 'tip of the iceberg' of galaxies to unveil a hidden era of star formation.

What do Mars and Iceland have in common? These days, not so much. But more than 4.5 billion years ago, it's possible the Red Planet had a crust comparable to Iceland today. This discovery, hidden in the oldest martian fragments found on Earth, could provide information about our planet that was lost over billions of years of geological movement and could help explain why the Earth developed into a planet that sustains a broad diversity of life and Mars did not.

NASA has revealed groundbreaking new views of the cosmos from the James Webb Space Telescope. The images include the deepest infrared view of our universe that has ever been taken.

The first ever exoplanets were discovered 30 years ago around a rapidly rotating star, called a pulsar. Now, astronomers have revealed that these planets may be incredibly rare.

The first full-color image from NASA's James Webb Space Telescope reveals thousands of galaxies, including the faintest objects ever observed in the infrared.

In 2019, astronomers observed the nearest example to date of a star that was shredded, or 'spaghettified,' after approaching too close to a massive black hole. That tidal disruption of a sun-like star by a black hole 1 million times more massive than itself took place 215 million light years from Earth. Luckily, this was the first such event bright enough that astronomers could study the optical light from the stellar death, specifically the light's polarization, to learn more about what happened after the star was torn apart.

When NASA's OSIRIS-REx spacecraft arrived at the asteroid Bennu, scientists discovered something surprising: The asteroid's surface wasn't smooth like many were expecting but was covered in large boulders. Now, a team of physicists think they know why.

A team of physicists has developed a method for predicting the composition of dark matter -- invisible matter detected only by its gravitational pull on ordinary matter and whose discovery has been long sought by scientists.
