Scientists have a good estimate on the staggering number of stars in the universe.
The James Webb Space Telescope is the biggest orbital telescope ever built and is scheduled to be launched into space on Dec. 18, 2021.
The largest orbital telescope ever made will allow astronomers to study the atmospheres of alien planets, learn about how stars form in the Milky Way and peer into the farthest reaches of the universe.

By studying the chemical makeup of binary stars, astronomers found many planetary systems are far less peaceful than ours.

Billions of galaxies are in the universe, with billions of stars in every galaxy. Could billions of planets be out there too?
Weather on other planets and moons can be much more extreme than on Earth.
Proxima Centauri is the closest star to the solar system and is home to a potentially habitable planet.

Astronomers just measured the largest flare ever from Proxima Centauri, humanity’s closest neighboring star. These flares could be bad news for life trying to develop on a planet orbiting the star.
A planet in a triple-star system has been discovered.
Publicly available data and collaborations between scientists have led to the discovery of a planet in a triple-star system.

This discovery will shape the hunt for life on exoplanets.
In the future, robots we’ve programmed may evolve and multiply on distant planets.
The robots are 'born' via 3D printer, and recycle themselves upon their 'death'.

We observed a powerful flare and a huge burst of radio waves from our nearest stellar neighbour, Proxima Centauri, indicating violent space weather around the star.
Many people who say they have seen UFOs are either dog walkers or smokers.

Scientists are not convinced by the current evidence of UFOs. That doesn’t mean that they don’t exist. But have Americans’ belief in UFOs gone from science to a new religion?

The primary objective of CHEOPS is to better understand the planets that we’ve already found. And its mission is now in full swing.

Why isn’t there an endless variety of planets in the universe? An astrophysicist explains why planets only come in two flavors.
