Cygnus X-1 is the heaviest stellar black hole observed without using gravitational waves The first black hole ever discovered still has a few surprises in store. New observations of the black hole–star pair called Cygnus X-1 indicate that the black hole weighs about 21 times as much as the sunContinue Reading
This was the most precise landing of all time. NASA’s rhinoceros-size Perseverance rover pulled off the most precise landing in Martian history Thursday (Feb. 18), touching down successfully in Jezero crater. The landing put the mobile robot laboratory in position to begin the hunt for signs of long-lost life inContinue Reading
On Feb. 18, NASA’s newest Mars rover, Perseverance, will descend into the Red Planet’s atmosphere, braving temperatures equivalent to those on the surface of the sun as it deploys a supersonic parachute in hopes of a safe landing. Earthbound viewers can follow the nail-biting action at home here on LiveContinue Reading
