Beyond Our Solar System

Hubble captured this massive galaxy cluster, called Abell 1351, with its Wide Field Camera 3 and Advanced Camera for Surveys.

With its mirror segments aligned and its scientific instruments undergoing calibration, Webb is just weeks from full operation.

Completing a nearly 30-year marathon, Hubble has calibrated more than 40 "milepost markers" of space and time.

These Jupiter-sized worlds are so close to their parent star that they are being roasted at temperatures above 3,000 degrees Fahrenheit.

Hubble has established an extraordinary new benchmark: detecting the light of the farthest individual star ever seen to date.

This cosmic portrait – captured by Hubble – shows a stunning view of the spiral galaxy NGC 4571.

The number of confirmed exoplanets has crossed the 5,000 mark.

Smashups between rocky bodies shaped our solar system. Astronomers report the first observations of a debris cloud from one of these collisions.

The Webb team expects the telescope's optical performance will be able to meet or exceed the science goals the observatory was built to achieve.

A design quirk in the X-ray observatory has made it possible for astronomers to use previously unwanted light to study more cosmic objects than before.

A supermassive black hole 9 billion light-years away appears to have a companion black hole orbiting around it.

The team has successfully worked through the second and third out of seven total phases of mirror alignment.

A spectacular head-on collision between two galaxies fueled the unusual triangular-shaped star-birthing frenzy.

Five years ago, astronomers revealed a spectacular collection of other worlds: the TRAPPIST-1 system.

One of the most exciting findings in planetary science in recent years is the discovery of interstellar objects passing through our solar system.

NASA’s Imaging X-Ray Polarimetry Explorer has delivered its first imaging data since completing its month-long commissioning phase.

The James Webb Space Telescope is nearing completion of the first phase of the months-long process of aligning the observatory’s primary mirror.

This Hubble image seems incredibly three-dimensional for a piece of deep-space imagery.

NGC 1705 is a cosmic oddball – it is small, irregularly shaped, and has recently undergone a spate of star formation known as a starburst.

By happy coincidence, the interaction of these galaxies resembles the starship known as the USS Enterprise from Star Trek!

Dr. Laurie Leshin has been appointed as director of NASA's Jet Propulsion Laboratory (JPL) in Southern California.

The spiral arms of the galaxy NGC 3318 are lazily draped across this image from the NASA/ESA Hubble Space Telescope.

NASA’s James Webb Space Telescope team will answer questions about the mission’s latest milestones on Jan. 24.

A black hole at the heart of the dwarf galaxy Henize 2-10 is creating stars rather than gobbling them up.

An international research team will survey the stars, star clusters, and dust that lie within 19 nearby galaxies.
