Scientists find a giant hot neighbor for the star Vega

Astronomers have discovered new hints of a giant, scorching-hot planet orbiting Vega, one of the brightest stars in the night sky. The research, published this...

Scientists catch a moving supermassive black hole

Scientists have long theorized that supermassive black holes can wander through space--but catching them in the act has proven difficult. Now, researchers at the Center...

How the habitability of exoplanets is influenced by their rocks

The conditions on Earth are ideal for life. Most places on our planet are neither too hot nor too cold and offer liquid water. These and...

Scientists find source of highest-energy cosmic rays in the galaxy

A long-time question in astrophysics appears to finally be answered, thanks to a collection of large, high-tech water tanks on a mountainside in Mexico. The...

Scientists detect gigantic jet spied from black hole in early universe

Astronomers may have discovered the most distant jet emitting X-rays. The source of this jet is a rapidly growing supermassive black hole, or quasar, located...

How fast is the universe expanding

Despite a century of measurements, astronomers can’t agree on the rate at which the universe is expanding. A technique that relies on measuring distances to...

Scientists find the third-nearest star with a planet—and it’s rocky like Earth

In the past two decades, scientists have discovered more and more planets orbiting distant stars—but in some sense, they’re still just dots on a...

Scientists find a new hot neighbor for our Earth

A rocky planet discovered in the Virgo constellation could change how we look for life in the universe. A newly discovered planet could be our...

Volcanoes might light up the night sky of our Earth

Until now, researchers have found no evidence of global tectonic activity on planets outside our solar system. On Earth, plate tectonics is not only responsible...

This may solve the mystery of the expansion of the universe

The universe was created by a giant bang; the Big Bang 13.8 billion years ago, and then it started to expand. The expansion is ongoing:...
