WRT #Hubble issues: just because there’s little news from @NASA does not mean that all hope is lost. It is an old spacecraft and there are still many options that have yet to be taken. So dial back the gossip and cross your fingers. Hubble is still a badass telescope. #astronomy

670 light-years away, KELT-9b weighs in at nearly three times the mass of Jupiter. With a surface temp of 7,800 degrees F (4,300 C), hydrogen molecules are likely ripped apart, unable to re-form until their atoms flow around to the planet’s nightside.

The High Resolution Camera (HRC) is used at the focus of Chandra, where it detects X-rays reflected from an assembly of 8 mirrors. The HRC can reveal detail as small as 1/2 an arc second — equivalent to being able to read a newspaper at a distance of half a mile! #CameraDay
