Hubble Observes Creative Destruction as Galaxies Collide

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...
Based on measurements gathered by the Copernicus Sentinel-5P mission between April 2018 and March 2019, the image shows nitrogen dioxide over Europe. Nitrogen dioxide pollutes the air mainly as a result of traffic and the combustion of fossil fuel in industrial processes. It has a significant impact on human health, contributing particularly to respiratory problems.

The air we breathe

Air pollution is a major concern of the new civilized world, which has a serious toxicological impact on human health and the environment. It...

Open cluster NGC 2682 at least two times larger than previously thought

NGC 2682 is a nearby open cluster, approximately 3.5 Gyr old. Dynamically, most open clusters should dissolve on shorter timescales, of ~ 1 Gyr....

Earth vs. asteroids: humans strike back

Incoming asteroids have been scarring our home planet for billions of years. This month humankind left our own mark on an asteroid for the...
The Southern Crab Nebula — Hubble’s 29th anniversary image.

Unrivaled View of the Southern Crab Nebula

This incredible image of the hourglass-shaped Southern Crab Nebula was taken to mark the NASA/ESA Hubble Space Telescope’s 29th anniversary in space. The nebula,...
The asteroid 6478 Gault is seen with the NASA/ESA Hubble Space Telescope, showing two narrow, comet-like tails of debris that tell us that the asteroid is slowly undergoing self-destruction. The bright streaks surrounding the asteroid are background stars. The Gault asteroid is located 214 million miles from the Sun, between the orbits of Mars and Jupiter. Credit: NASA, ESA, K.

Hubble Captures Rare Active Asteroid

Thanks to an impressive collaboration bringing together data from ground-based telescopes, all-sky surveys and space-based facilities — including the NASA/ESA Hubble Space Telescope —...
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

The mass of the Milky Way is one of the most fundamental measurements astronomers can make about our galactic home. However, despite decades of...

Milky Way’s galactic collision with Andromeda to happen earlier than previously thought

According to a new study, the galactic collision of Milky Way with its largest neighbor, the starry Andromeda, will happen earlier than previously thought. The...
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

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...
