This artist's illustration shows what one of the very first galaxies in the Universe might have looked like. High levels of violent star formation and star death would have illuminated the gas filling the space between stars, making the galaxy largely opaque and without a clear structure.

Universe’s earliest galaxies were brighter than expected

Using NASA's Spitzer Telescope, astronomers have recently found cues on how galaxies lit up the universe. According to their findings, some of the Universe's...
Astronomers developed a mosaic of the distant Universe, called the Hubble Legacy Field, that documents 16 years of observations from the NASA/ESA Hubble Space Telescope. The image contains 200,000 galaxies that stretch back through 13.3 billion years of time to just 500 million years after the Big Bang. The new set of Hubble images, created from nearly 7,500 individual exposures, is the first in a series of Hubble Legacy Field images. The image comprises the collective work of 31 Hubble programs by different teams of astronomers. Hubble has spent more time on this small area than on any other region of the sky, totaling more than 250 days, representing nearly three-quarters of a year. The team is working on a second set of images, totaling more than 5,200 Hubble exposures, in another area of the sky.

2,65,000 galaxies in an extensive legacy field mosaic

NASA's Hubble Space Telescope has recently captured an image of a legacy field, showing 2,65,000 galaxies, each at different stages in their life cycles,...
his Hubble Space Telescope image represents a portion of the Hubble Legacy Field, one of the widest views of the universe ever made. The image, a combination of thousands of snapshots, represents 16 years' worth of observations. The Hubble Legacy Field includes observations taken by several Hubble deep-field surveys, including the eXtreme Deep Field (XDF), the deepest view of the universe. The wavelength range stretches from ultraviolet to near-infrared light, capturing all the features of galaxy assembly over time. This cropped image mosaic presents a wide portrait of the distant universe and contains roughly 200,000 galaxies. They stretch back through 13.3 billion years of time to just 500 million years after the universe's birth in the big bang. Credits: NASA, ESA, G. Illingworth and D.

Two neutron stars collided near the solar system billions of years ago

Two neutron stars collided near the solar system billions of years ago

A growing body of evidence indicates that binary neutron-star mergers are the primary origin of heavy elements produced exclusively through rapid neutron capture. As...
Artist’s impression of V404 Cygni seen close up. The binary star system consists of a normal star in orbit with a black hole. Material from the star falls towards the black hole and spirals inwards in an accretion disk, with powerful jets being launched from the inner regions close to the black hole. Credit: ICRAR

Black hole nine times larger than the sun is pulling in space and time

Recently, astronomers have detected fast - powerful, relativistic, swirling jets coming from a black hole that lies about 8000 light-years from Earth. The black...

Hubble captured a crowded cluster Messier 75

Recently, the NASA/ESA Hubble Space Telescope’s Advanced Camera has captured the image of Messier 75, a sparkling burst of stars. Messier 75 is a...

Hubble measurements confirmed: Universe is outpacing all expectations of its expansion rate

The universe is expanding about 9% faster than expected based on its trajectory seen shortly after the big bang. This new revelation is made...
