In 1974, Stephen Hawking made a prediction that transformed our understanding of black holes. Black holes, he showed, are not truly black: They slowly lose energy through a quantum process now known as Hawking radiation. The lighter the black hole, the faster it evaporates.

As the BepiColombo mission prepares to enter the final phase of its journey to Mercury, a series of studies conducted by researchers at the University of Liège and KU Leuven sheds new light on the early stages of the evolution of the planet closest to the sun. Using experimental petrology, the researchers are reconstructing in […]

Star formation in galaxies is closely linked to molecular gas. In the distant past, when galaxy interactions were more common, these encounters compressed molecular gas, causing dense clouds to collapse under their own gravity and form new stars.

A private spacecraft that was supposed to supply a lifeline to NASA’s Swift Observatory managed to get close to the sinking telescope and even snap photos more than a week after the rescue was abandoned.

There are myriad ways of “being a star,” and scientists spend years trying to uncover and understand them. One unusual type is the so-called hot subdwarf—small stars that burn mysteriously hot for their size. Scientists from the Faculty of Physics and the Faculty of Mathematics and Informatics at Vilnius University (VU) are working to explain […]

This NASA/ESA Hubble Space Telescope image features a sprawling cosmic vista in the Large Magellanic Cloud, or LMC, the largest of the small galaxies that orbit our Milky Way galaxy. At just 160,000 light-years away, the LMC offers a close look at highly active star-forming sites like the one in this image. This photogenic nebula, […]

Two Mercury-bound spacecraft left their mother ship behind on Thursday and headed down the home stretch of their nearly decade-long voyage to the solar system’s smallest and closest-to-the-sun planet.

Recent observations with NASA’s Hubble Space Telescope have revealed a giant, evolving, 10-sided atmospheric wave encircling Saturn’s south pole. This discovery marks the first time a large, regular-sided jet pattern has been observed in the planet’s southern hemisphere. The feature appears remarkably similar to Saturn’s famous hexagon at its north pole but is also distinctly […]
