Hubble telescope spots a black hole fostering baby stars in a dwarf galaxy

Black holes can not only separate stars, but they can also trigger star formation, as scientists have now seen in a nearby dwarf galaxy. At the centers of most, if not all, large galaxies are supermassive black holes with masses millions to billions of times larger than the Earth’s Sun. For example, in the heart … Read more

James Webb telescope is headed for Lagrange point 2

The James Webb Space Telescope (JWST) is approaching its new home. On January 24, it will arrive at a point in space that scientists call Lagrange Point 2, or L2. This is the technical name for a sensitive gravitational breaking point. JWST is tied to the place where, in the Earth-Sun pair, the Earth’s gravitational … Read more

James Webb Space Telescope marks deployment of all mirrors

NASA’s massive new observatory has marked another milestone. After nearly a month spent in space, the James Webb Space Telescope, also known as JWST or Webb, is nearing the end of its work. A complicated series of setups has led to the transformation of the telescope from a tightly folded launch configuration to what looks … Read more

Here’s how the James Webb Space Telescope is aligning its mirrors in deep space

The James Webb Space Telescope continues to fine-tune its mirrors to finally peek into deep and distant space. The telescope was launched on December 25 with 18 hexagonal segments of its primary mirror and secondary mirror folded and stored to allow components to survive the rigidity of lifting. Now the telescope is close to its … Read more

You’ve Got a Rare Chance to See a Huge Asteroid Fly by Earth This Week. Here’s How

In a slow-moving universe, asteroids give us a rare opportunity to see how things move in real time. Such a chance comes to us on the evening of Tuesday, January 18, when the 1.1-kilometer asteroid (7482) 1994 PC1 travels 1.23 million miles (1.98 million kilometers) from Earth. This is about five times the distance from … Read more
