Nearby galaxy in Triangulum

This face-on spiral galaxy – Messier 33 aka M33 – is the second-closest spiral to our Milky Way at 3 million light-years away.

Amazing views of Saturn’s icy moon Dione

The Cassini spacecraft made its final flyby of Saturn’s moon Dione last week. Check out the spacecraft’s final breathtaking close views.

This extraordinary bubble, glowing like the ghost of a star in the haunting darkness of space, may appear supernatural and mysterious, but it is a familiar astronomical object: a planetary nebula, the remnants of a dying star. This is the best view of the little-known object ESO 378-1 yet obtained and was captured by ESO’s Very Large Telescope in northern Chile. Image credit: ESO

Charting the slow death of the universe

A study of 200,000 galaxies found they had lost half their energy in just 2 billion years.

EGSY8p7 is the most distant confirmed galaxy whose spectrum obtained with the W. M. Keck Observatory places it at a redshift of 8.68 at a time when the universe was less than 600 million years old. The illustration shows the remarkable progress made in recent years in probing early cosmic history. Such studies are important in understanding how the Universe evolved from an early dark period to one when galaxies began to shine. Hydrogen emission from EGSY8p7 may indicate it is the first known example of an early generation of young galaxies emitting unusually strong radiation.

Astronomers measure most distant galaxy

The galaxy, called EGSY8p7, is about 13.2 billion light-years away. That means astronomers are now seeing it as it existed just 600 million years after the Big Bang.
