Jupiter will make its closest approach to Earth next week

Jupiter, the fifth planet from the Sun and the largest in the Solar System- is at its biggest and brightest this month. Next week,...
The unique capabilities of the SPHERE instrument on ESO’s Very Large Telescope have enabled it to obtain the sharpest images of a double asteroid as it flew by Earth on 25 May. While this double asteroid was not itself a threatening object, scientists used the opportunity to rehearse the response to a hazardous Near-Earth Object (NEO), proving that ESO’s front-line technology could be critical in planetary defence. The left-hand image shows SPHERE observations of Asteroid 1999 KW4. The angular resolution in this image is equivalent to picking out a single building in New York — from Paris. An artist's impression of the asteroid pair is shown on the right. Credit: ESO

Comet inspires chemistry for making breathable oxygen on Mars

Although plentiful in modern Earth’s atmosphere, molecular oxygen is extremely rare in space. Only trace amounts have been found elsewhere in our solar system...

Moon formation brought water to the Earth

Earth is the only terrestrial planet with a large amount of water and a relatively large moon, which stabilizes the Earth's axis. Earth grew...

What does Earth’s core have in common with salad dressing?

This magnetic field is formed deep inside the earth in a fluid outer core of iron and other elements that creates electric currents. The...

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...
