    New observations of the first black hole ever detected have led astronomers to question what they know about the Universe’s most mysterious objects.

    Published today in the journal Science, the research shows the system known as Cygnus X-1 contains the most massive stellar-mass black hole ever detected without the use of gravitational waves.

    Cygnus X-1 is one of the closest black holes to Earth. It was discovered in 1964 when a pair of Geiger counters were carried on board a sub-orbital rocket launched from New Mexico.

    The object was the focus of a famous scientific wager between ...

    Touchdown! NASA’s Mars Perseverance Rover Safely Lands on Red Planet

    February 18, 2021, Categories  Astronomy/Space, Biology/Biotechnology, Environment/Geology

    Members of NASA’s Perseverance Mars rover team watch in mission control as the first images arrive moments after the spacecraft successfully touched down on Mars, Thursday, Feb. 18, 2021, at NASA’s Jet Propulsion Laboratory in Pasadena, California. A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith.

    Astronomers have tested a method for reconstructing the state of the early Universe by applying it to 4000 simulated universes using the ATERUI II supercomputer at the National Astronomical Observatory of Japan (NAOJ). They found that together with new observations the method can set better constraints on inflation, one of the most enigmatic events in the history of the Universe...

    New theory explains possible origin of plummeting Chicxulub impactor that struck off Mexico

    New theory explains possible origin of the Chicxulub impactor. It was tens of miles wide and forever changed history when it crashed into Earth about 66 million years ago.

    The Chicxulub impactor, as it’s known, left behind a crater off the coast of Mexico that spans 93 miles and goes 12 miles deep. Its devastating impact brought the reign of the dinosaurs to an abrupt and calamitous end by triggering their sudden mass extinction, along with the end of almost three-quarters of the plant and animal species then living on Earth.

    The enduring puzzle has always been where the asteroid or comet that set off the destruction originated, and how it came to strike the Earth...
