Hubble’s 28th Anniversary

[music throughout] In April 2018, the Hubble Space
Telescope premiered this image of the Lagoon Nebula The image honors Hubble’s 28th
year in orbit. Even after 27 years, Hubble
continues to further humanity’s knowledge of the universe Here are several science
achievements from Hubble’s latest year of observations. Within our own solar system, Hubble observed Neptune’s shrinking storm, an asteroid that split in half
5000 years ago and is sprouting a comet tail, and the farthest active inbound
comet, nicknamed “K2.” Exploring beyond our solar
system, Hubble astronomers discovered
many new characteristics of planets around other stars, from finding that water is
common in these “exoplanet” atmospheres, to finding different types of
atmospheres among large planets called “hot Jupiters.” Hubble observed four Earth-sized
planets in the habitable zone of the star TRAPPIST-1. The observations showed no signs
of thick, puffy atmospheres on at least three planets, increasing the likelihood that
these are rocky, terrestrial planets. Hubble observed visible light
from the first identified source of gravitational waves, created
when two neutron stars collided. With Hubble data, astronomers
used graviational lensing to determine the mass of a white
dwarf star. Hubble observed a massive dying
star being reborn as a black hole. Hubble witnessed light from a
supernova explosion reflecting off a dust cloud, which created
this “light echo.” Astronomers using Hubble refined
the Hubble constant. This revealed that the expansion
of our universe is accelerating even faster than expected. And Hubble premiered a
360-degree fly-through of the Orion Nebula… so that those of us down on
Earth can imagine flying amongst the stars. [music] For more information about

  1. Hubble never ceases to amaze me Happy Birthday Hubble #Hubble28

  2. And all these achievements continue, despite her optics and electronics starting to degrade because of solar radiation. Why waste a good thing? Refurbish and re-fly her!
    (But finish and fly the JWST first.)

  3. Beautiful pics. The Orion Nebula fly thru is a must-see. SAVE HUBBLE!. Someone grab it and bring it back (Space X). It's given us too much to just burn up. Not a fitting end at all.

  4. they revised the hubble constant. what a sad joke. the universe is not expanding. its called intrinsic red shift.
