Astronomers have discovered the closest known black hole to Earth, just 1,600 light-years away. Scientists reported Friday that this black hole is 10 times more massive than our sun. And it’s three times closer than the previous record-holder. It was identified by observing the motion of its companion star, which orbits the black hole at about the same distance as Earth orbits the sun. The black hole was initially identified using the European Space Agency’s Gaia spacecraft, said Kareem El-Badry of the Harvard-Smithsonian Center for Astrophysics. Astronomers using the International Gemini Observatory, operated by NSF’s NOIRLab, have discovered the closest-known black hole to Earth.

A giant slab of ice bigger than the Spanish island of Majorca has sheared off from the frozen edge of Antarctica into the Weddell Sea, becoming the largest iceberg afloat in the world, the European Space Agency said on Wednesday. The newly calved berg, designated A-76 by scientists, was spotted in recent satellite images captured by the Copernicus Sentinel-1 mission, the space agency said in a statement posted on its website with a photo of the enormous, oblong ice sheet. A view of the newly calved iceberg designated A-76 by scientists, the largest currently afloat in the world according to the European Space Agency (ESA), and captured by the ESA's Copernicus Sentinel-1 mission is seen in this handout photo obtained by Reuters on May 20, 2021.
