Hubble Observes Creative Destruction as Galaxies Collide

Space
The NASA/ESA Hubble Space Telescope has taken a new look at the spectacular irregular galaxy NGC 4485, which has been warped and wound by...
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

Space
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.

Hubble captured a crowded cluster Messier 75

Space
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...
This is a ground-based telescope’s view of the Large Magellanic Cloud, a satellite galaxy of our Milky Way. The inset image, taken by the Hubble Space Telescope, reveals one of many star clusters scattered throughout the dwarf galaxy. Credit: NASA, ESA, Adam Riess, and Palomar Digitized Sky Survey

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

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

Hubble spotted a mysterious dark spot on Neptune

Space
Since it’s a discovery in the mid-19th century, Neptune has consistently been a planet of mystery. As the farthest planet from our Sun, Neptune-...
This artist’s impression shows a computer generated model of the Milky Way and the accurate positions of the globular clusters used in this study surrounding it. Scientists used the measured velocities of these 44 globular clusters to determine the total mass of the Milky Way, our cosmic home. Credit: ESA/Hubble, NASA, L. Calçada

Hubble & Gaia accurately weigh the Milky Way

Space
The mass of the Milky Way is one of the most fundamental measurements astronomers can make about our galactic home. However, despite decades of...
Deep within the glowing cloud of the HII region LHA 120-N 180B, MUSE has spotted a jet emitted by a fledgling star — a massive young stellar object . This is the first time such a jet has been observed in visible light outside the Milky Way. Usually, such jets are obscured by their dusty surroundings, meaning they can only be detected at infrared or radio wavelengths by telescopes such as ALMA. However, the relatively dust-free environment of the LMC allowed this jet — named Herbig–Haro 1177, or HH 1177 for short — to be observed at visible wavelengths. At nearly 33 light-years in length, it is one of the longest such jets ever observed. This annotated image shows a close-up of the jet source and the bow shocks formed by the jet interacting with surrounding gas. Credit: ESO, A McLeod et al.

Bubbles of brand new stars

Space
This dazzling region of newly-forming stars in the Large Magellanic Cloud (LMC) was captured by the Multi Unit Spectroscopic Explorer instrument (MUSE) on ESO’s...
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...
