Every second, a star dies in the universe. But these stellar beings don't just completely vanish, stars always leave something behind.

Some stars explode in a supernova, turning into a black hole or a neutron star, while the majority of stars become white dwarfs, a core of the star it once used to be. However, a new study reveals that these white dwarfs contribute more to life in the cosmos than previously believed.

Fossils can tell scientists a lot about prehistoric life, but they can’t say everything. When it comes to understanding our animal and plant forebears, there’s a lot we’ll probably never learn from fossils, like what colors ancient animals were. However, in rare cases, researchers get lucky. In a new paper published in the journal, Proceedings of the Royal Society B, by a team of researchers at the Nanjing Institute of Geology and Paleontology, the group identified the true colors of three ancient insects that were preserved in amber—an incredibly rare find for paleontologists.

The insects can be dated back to the Cretaceous period, which occurred 99 million years ago. The animals were all preserved in pieces of amber from a mine in northern Myanmar. The insects—a beetle, a fly, and a wasp—are so well-preserved in the amber that their true color could be identified.

Some young people in Alabama are throwing Covid-19 parties, a disturbing competition where people who have coronavirus attend and the first person to get infected receives a payout, local officials said.

The parties are being held in Tuscaloosa, and infected people are urged to attend so others can intentionally contract the virus.

Valeria Souza Saldívar never planned to devote her life to a remote and ancient oasis more than 1000 kilometers north of her laboratory in Mexico City. But a call in early 1999 changed that.

“It’s one of the best cold calls I’ve ever made,” says James Elser, a limnologist at the University of Montana. He had picked up the phone to invite Souza Saldívar to join a NASA-funded astrobiology project in Cuatro Ciénegas—a butterfly-shaped basin with colorful pools, or pozas, in the middle of Mexico’s Chihuahuan Desert.

Neither Souza Saldívar, a microbial ecologist at the National Autonomous University of Mexico, University City, nor her ecologist husband and research partner Luis Eguiarte Fruns, also at UNAM, had ever visited Cuatro Ciénegas. That first trip convinced them to completely change their research plans. “Looking at those mountains and the water, I fell in love,” Souza Saldívar says.

In the strange field of quantum physics, quantum entanglement – what Einstein called "spooky action at a distance" – stands out as one of the most intriguing phenomena. And now scientists just managed to successfully demonstrate it again, this time onboard a CubeSat satellite orbiting Earth.

A team of German astronomers has discovered two super-Earths near the red dwarf star Gliese 887 and just a short 11 light-years away from Earth.

Super-Earths are planets with a mass greater than Earth's, but less than those of the ice giants Uranus and Neptune. The two exoplanets -- or planets located outside of our solar system -- were named Gliese 887b and Gliese 887c, respectively.

Tiny antibodies found in alpacas could help suppress a second wave of coronavirus and allow countries to safely lift lockdown, researchers have claimed.

Scientists in Sweden and South Africa have used 'nanobodies' from an animal immunised against the virus to prevent it from binding or infecting a human being.

The small antibody targets the spikes of the virus which in turn interferes with its ability to infect its host.

NASA has released a stunning 10-year time-lapse video of the Sun, bringing a decade of activity into a one-hour film.

NASA's Solar Dynamics Observatory (SDO) has been watching the Sun non-stop for over a full decade. While orbiting around the Earth, SDO has gathered 425 million high-resolution images of the Sun, NASA said in a statement while releasing the time-lapse footage.
