Life After Death: Astronomers Find a Planet That Shouldn't Exist

The star would have inflated up to 1.5 times the planet's orbital distance -- engulfing the planet in the process -- before shrinking to its current size at only one-tenth of that ...

Exoplanet May Reveal Secrets About the Edge of Habitability

How close can a rocky planet be to a star, and still sustain water and life? A recently discovered exoplanet may be key to solving that ...

Key Building Block for Life Found at Saturn's Moon Enceladus

The search for extraterrestrial life in our solar system just got more exciting. A team of scientists has discovered new evidence that the subsurface ocean of Saturn's moon Enceladus contains a key building block for life. The team directly detected phosphorus in the form of phosphates originating ...

Mysterious Dashes Revealed in Milky Way's Center

In the early 1980s, astronomers discovered gigantic, one-dimensional filaments dangling vertically near Sagittarius A*, our galaxy's central supermassive black hole. Now, astronomers have discovered a new population of filaments -- but these threads are much shorter and lie horizontally or ...

Jupiter's Moon Europa May Have Had a Slow Evolution

Europa may have a metamorphic origin for the ocean. While some scientists speculated this, a research team shows that if Europa indeed formed from hydrated rocks (i.e., rocks have hydrogen and ...

Navigating Underground With Cosmic-Ray Muons

Superfast, subatomic-sized particles called muons have been used to wirelessly navigate underground in a reportedly world first. By using muon-detecting ground stations synchronized with an ...

Researchers Demystify the Unusual Origin of the Geminids Meteor Shower

Princeton researchers used observations from NASA's Parker Solar Probe mission to deduce that it was likely a violent, catastrophic event -- such as a high-speed collision with another body or a ...

The discovery of a rare type of white dwarf star system provides new understanding into stellar ...

Scientists Report 'Benchmarks' for Extreme Space Weather

Extreme space weather threatens vital satellites orbiting the Earth, including the Global Navigation Satellite Systems (GNSS) which pass through the heart of the outer radiation belt. New research ...

Astronomers Discover New Link Between Dark Matter and Clumpiness of the Universe

Researchers reveal a theoretical breakthrough that may explain both the nature of invisible dark matter and the large-scale structure of the universe known as the cosmic web. The result establishes a ...

Earth Was Created Much Faster Than We Thought: This Makes the Chance of Finding Other Habitable Planets in the Universe More Likely

Over the past decades, researchers thought Earth was created over a period of more than 100 million years. However, a new study from suggests that the creation of Earth was much more rapid, and that ...

A Scorching-Hot Exoplanet Scrutinized by Astronomers
