Planck found the Hubble constant to be 46,200 mph per million light-years (67.4 km/s/Mpc) in 2018. A Hubble Space Telescope image shows RS Puppis, one of the brightest Cepheids visible in our galaxy.

This Hubble Telescope image shows a doubly-imaged quasar, which can be used to measure the Hubble constant. A new technique of measuring the Hubble Constant from such doubly-imaged quasar systems ...

Space Telescope Live: NASA, ESA, CSA, STScI, and CDS. The images you see on the tracker aren’t the live images being pulled straight from the telescope, as that data still needs to be processed.

The Washington County Museum opens its new exhibit space at the Hillsboro Civic Center on Nov. 17 with a 2,500-square foot exhibit of the Hubble telescope, a secondary exhibit of the Bracero farm ...

Every Hubble anniversary feels like a triumph for the elderly space telescope. It may have a few more anniversaries left in it. NASA hopes it will continue operations into the 2030s. Long live Hubble.

An event combining virtual reality and live musical performance aims to bring together a 20-piece orchestra, a 100-person choir and breathtaking views of the cosmos captured by the Hubble Space ...

Hubble’s pointing system is so precise, NASA says it is the equivalent of being able to keep a laser shining on a dime over 200 miles away for however long Hubble takes a picture – up to 24 hours.

Celebrate the invention of the Hubble telescope with a two-hour special on the Science Channel, which premieres Sunday, April 19, at 8 p.m. ET on the Discovery and Science channels. Viewers can ...

Hubble, he told me, was not pointing where it should, and it didn’t know it. Usually, Hubble aligns on its observational targets with a degree of accuracy found in few other spacecraft.

Every Hubble anniversary feels like a triumph for the elderly space telescope. It may have a few more anniversaries left in it. NASA hopes it will continue operations into the 2030s. Long live Hubble.
