This comet is due to pass closest to our sun and Earth in December 2018. It’s already the brightest comet in the night sky, visible to astronomers with telescopes and binoculars. A new image shows the comet’s rotation!
There’s a new robot on Mars’ surface, the InSight spacecraft, designed to study the planet’s interior. It set down safely Monday after nearly 7 months of flight from Earth and a 7-minute nail-biting plummet through Mars’ thin atmosphere.
Signals from Mars will take 8 minutes to travel to Earth on Monday. By the time we hear that InSight has reached the top of Mars’ atmosphere, the lander will have already touched down safely … or crashed.
On November 26, 2018, NASA’s InSight lander will make its daring descent to Mars’ surface. NASA engineers hope to broadcast word of a successful touchdown at 20:00 UTC (3 p.m. EST), with live landing commentary starting about an hour before.
“If you were a Martian coming to explore Earth’s interior, it wouldn’t matter if you put down in the middle of Kansas or the beaches of Oahu … The beauty of this mission is happening below the surface.”
Last month, the International Astronomical Union – same organization that demoted Pluto to dwarf planet status – voted to rename Hubble’s law as the Hubble–Lemaître law. Will astronomers use the new name?
