This artist’s impression shows how J043947.08+163415.7, a very distant quasar powered by a supermassive black hole, may look close up. This object is by far the brightest quasar yet discovered in the early Universe.

Hubble sees the brightest quasar in the early Universe

Space
The NASA/ESA Hubble Space Telescope has discovered the brightest quasar ever seen in the early Universe. After 20 years of searching, astronomers have identified...
IC 63 — nicknamed the Ghost Nebula — is about 550 light-years from Earth. The nebula is classified as both a reflection nebula — as it is reflecting the light of a nearby star — and as an emission nebula — as it releases hydrogen-alpha radiation. Both effects are caused by the gigantic star Gamma Cassiopeiae. The radiation of this star is also slowly causing the nebula to dissipate. Credit:ESA/Hubble, NASA

Hubble captures the ghost of Cassiopeia

Space
About 550 light-years away in the constellation of Cassiopeia lies IC 63, a stunning and slightly eerie nebula. Also known as the ghost of...
Astronomers have just assembled one of the most comprehensive portraits yet of the universe’s evolutionary history, based on a broad spectrum of observations by the Hubble Space Telescope and other space and ground-based telescopes. In particular, Hubble’s ultraviolet vision opens a new window on the evolving universe, tracking the birth of stars over the last 11 billion years back to the cosmos’ busiest star-forming period, about 3 billion years after the big bang. This photo encompasses a sea of approximately 15,000 galaxies — 12,000 of which are star-forming — widely distributed in time and space. This mosaic is 14 times the area of the Hubble Ultra Violet Ultra Deep Field released in 2014. Credits: NASA, ESA, P. Oesch (University of Geneva), and M. Montes (University of New South Wales)

Hubble paints picture of the evolving universe
