A team of astronomers has shed new light on the fascinating and complex process of planet formation. The research brings together observations of more than 80 young stars that might have planets forming around them, providing astronomers with a wealth of data and unique insights into how planets arise in different regions of our galaxy.

In a series of studies, a team of astronomers has shed new light on the fascinating and complex process of planet formation. The stunning images, captured using the European Southern Observatory’s Very Large Telescope (ESO’s VLT) in Chile, represent one of the largest ever surveys of planet-forming discs...

There are few things more peaceful and relaxing than a night under the stars. Through the holidays, many people head away from the bright city lights to go camping. They revel in the dark skies, spangled with myriad stars.

As a child, I loved such trips, and they helped cement my passion for the night sky, and for all things space.

One of my great joys as an astronomer is sharing the night sky with people. There is something wondrous about helping people stare at the cosmos through a telescope, getting their first glimpses of the universe’s many wonders. But we can also share and enjoy the night sky just with our own eyes—pointing out the constellations and the planets or discovering the joys of watching meteor showers.

It is easy to be bitten by the astronomy bug, and a co...

Here are the ins and outs of NASA’s First Launch of SLS and Orion. NASA is building Orion spacecraft, Space Launch System (SLS) rocket and the ground systems needed to send astronauts into deep space and core capabilities needed to enable the journey to Mars.

Orion’s first flight atop the SLS will not have humans aboard, but it paves the way for future missions with astronauts. During this flight, Exploration Mission-1 (EM-1), the spacecraft will travel thousands of miles beyond the moon over 3 wks. It will launch on the most powerful rocket in the world and fly farther than any spacecraft built for humans has ever flown...

Astronomers have used modern techniques to visualise data from ESA’s Hipparcos space astrometry mission in 3D. This offered insights into the distribution of nearby stars and uncovered new groupings of stars in the solar neighbourhood, shedding light on the origins of the stars in Orion and calling into question the existence of the Gould Belt – an iconic ring-shaped structure of stars in the Milky Way. The results show the potential of 3D visualisation of the solar neighbourhood, an approach which is of particular relevance to ESA’s Gaia mission which will map the Milky Way and Local Group in 3D with unprecedented sensitivity and accuracy.
