But there’s nothing to worry about, NASA officials stressed.
If you’ve looked at the news today, you’d be forgiven for thinking a huge asteroid is on track to collide with Earth the day before the 2020 US Presidential election.
NASA Hubble Space Telescope images of comet NEOWISE, taken on Aug. 8, zero in on the visitor’s coma, the gossamer shell of gas and dust that surrounds its nucleus as it is heated by the Sun. This is the first time Hubble has photographed a comet of this brightness at such resolution after this close of a pass by the Sun.

New images from NASA’s Chandra X-ray Observatory show small knots of metal-rich debris in the remnant of Kepler’s supernova, also known as SN 1604, are moving up to 37 million km per hour (23 million mph). These are extremely high speeds for an explosion that happened over 400 years ago as seen from Earth.
Aliens? Or a chunk of solid hydrogen? Which idea makes less sense?
The process won’t be complete until 2063
Take that, asteroid 2020 QG!
The act could even reveal how to look for life on alien planets.
