Hubble

In September, NASA deliberately crashed a spacecraft into an asteroid to test a potential planetary defense technique. To mark the publication of four scientific papers, NASA has released a video of the impact captured by the Hubble Space Telescope.

The James Webb Space Telescope is probing greater depths of space and time than other observatories. Now it's discovered galaxies with a structure like our own Milky Way 11 billion light-years away, challenging our understanding of galaxy formation.

Astronomers have detected an eerie glow of “ghost light” that could represent a previously unknown component of the solar system. Comparing data from two distinct viewpoints – Hubble and New Horizons – researchers discovered a dim, unexplained glow.

Astronomers have been keenly watching the asteroid Didymos since the historic DART mission successfully crashed a spacecraft into it last month. And now, Hubble has detected something unexpected – the asteroid has sprouted two tails.

Last week, NASA crashed a spacecraft into an asteroid, and now images have been released of the collision and aftermath from a suite of telescopes – including Hubble and James Webb in their first collaboration. One even shows a new 10,000-km tail.

NASA is now exploring how Hubble can remain operational further into the future with the help of SpaceX’s Dragon capsule, which might be used to dock with the telescope and shift it to a more stable orbit.

By now you’ve no doubt seen the first batch of images from NASA’s powerful new James Webb Space Telescope. But the scope of the achievement is hard to appreciate without context, so here they are side-by-side with Hubble’s views of the same regions.

Astronomers have discovered bizarre “blue blobs” in space. These blobs are clusters of young, blue stars that are isolated from any parent galaxy, suggesting they formed from a galactic “belly flop.”

NASA has released a huge new report that astronomers are calling Hubble’s magnum opus. Analyzing 30 years of data from the famous space telescope, the new study makes the most precise measurement yet of how fast the universe is expanding.

Hubble has spotted the most distant single star ever seen, about 12.9 billion light-years from Earth. The light from this star was emitted soon after the Big Bang, and has been magnified by a galaxy and stretched out by the expansion of the universe.

Astronomers have spotted two “invisible” galaxies hiding near the dawn of the universe. The team used radio waves to peer behind a curtain of dust, and the find suggests that there were far more galaxies in the early universe than previously thought.

Every year, the Hubble Space Telescope conducts a grand tour of the outer solar system planets, checking their turbulent atmospheres for changes in weather, storms, clouds and colors. This year’s shots are now in, revealing a few surprises.
