One Hubble picture is worth 15,000 words (make that galaxies)

17 August 2018 Astronomy Now

Famous for its “deep field” views of the cosmos, the Hubble Space Telescope has produced another stunning image combining ultraviolet, visible and infrared light, capturing 15,000 galaxies in various stages of evolutionary development in a single frame .

Spectroscopic survey probes uncharted depths of Hubble Ultra Deep Field

1 December 2017 Astronomy Now

Astronomers at the European Southern Observatory have conducted the deepest spectroscopic survey ever. They focused on the Hubble Ultra Deep Field, measuring distances and properties of 1600 very faint galaxies, including 72 galaxies that have never been detected before, even by Hubble itself.

ALMA uncovers insights into “Golden Age” of galaxy formation

22 September 2016 Astronomy Now

International teams of astronomers have used the Atacama Large Millimeter/submillimeter Array (ALMA) to explore the distant corner of the universe first revealed in the iconic images of the Hubble Ultra Deep Field (HUDF). These new ALMA observations are significantly deeper and sharper than previous surveys at millimetre wavelengths.

First stars formed even later than previously thought

2 September 2016 Astronomy Now

ESA’s Planck satellite has revealed that the first stars in the universe started forming later than previous observations of the Cosmic Microwave Background indicated. This new analysis also shows that these stars were the only sources needed to account for reionising atoms in the cosmos, having completed half of this process when the universe had reached an age of 700 million years.

Hubble’s vibrant view of a massive galactic gathering

23 May 2016 Astronomy Now

This incredible image from the NASA/ESA Hubble Space Telescope reveals thousands of colourful galaxies in the constellation of Leo, components of cluster known as MACS J1149.5+2223. This vibrant view of the early universe was captured as part of the Frontier Fields campaign, which aims to investigate galaxy clusters in more detail than ever before.

Hubble dares to look into Pandora’s Box

7 March 2016 Astronomy Now

Peering deep into the early universe, this picturesque parallel field observation from the NASA/ESA Hubble Space Telescope reveals thousands of colourful galaxies swimming in the inky blackness of space in the constellation Sculptor. This spectacular skyscape was captured during the study of the giant galaxy cluster Abell 2744, otherwise known as Pandora’s Box.
