As telescopes have become more powerful, it’s turned out our solar system is not the only game in town: There are millions of other planets out there in the galaxy. But we’re still teasing out […]

If we take out all the matter, neutrinos, dark matter, cosmic rays, and radiation from the deepest parts of the voids, the only thing left is empty space. I know it sounds like a paradox, […]

Black holes are considered cosmic gluttons, from which not even light can escape. That is also why the images of black holes at the center of the galaxy M87 and our Milky Way, published a […]

Even though we can explore the universe with great precision, there is still a lot we don’t know, according to Ulf Danielsson, professor of theoretical physics at Uppsala University. Besides doing research, he is keen […]

When it comes to finding baby, still-forming planets around young stars, the Atacama Large Millimeter/submillimeter Array (ALMA) observatory is astronomers’ most adept tool. ALMA has delivered many images of the protoplanetary disks around young stars, […]

At the heart of the Milky Way, just 27,000 light-years from Earth, there is a supermassive black hole with a mass of more than 4 million suns. Nearly all galaxies contain a supermassive black hole, […]

As humans began to explore outer space in the latter half of the 20th century, radio waves proved a powerful tool. Scientists could send out radio waves to communicate with satellites, rockets and other spacecraft, […]

An international team led by ICREA researcher Mark Gieles, from the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) and the Institute of Space Studies of Catalonia (IEEC), has developed a model that […]

The most massive stars in the universe are destined to explode as brilliant supernova before collapsing into black holes. Yet one huge star appears to have never fulfilled its destiny; in a twist of irony, […]

Is there anything more dramatic than an exploding star? More than just extraordinarily bright, energetic events that can light up the sky for months, these explosions play important roles in the cosmos. Supernovas create heavy […]
