Young star FU Orionis is pretty shocking! Astronomers used Hubble to observe the sizzling star in ultraviolet light. At 16,000 kelvins, nearly three times our sun’s surface temperature, its disk is nearly twice as hot as prior models have calculated: https://bit.ly/4fZwSU5

The Mikulski Archive for Space Telescopes is a treasure trove that includes data from various wavelengths. MAST hosts information from over a dozen telescopes like Webb, Hubble, TESS, and Kepler that’s free to everyone: https://archive.stsci.edu

A forming star in molecular cloud L1527 is the dot at the center. Why do near-and mid-infrared observations from the James Webb Space Telescope show such different views of its ejections? Find this answer, and more detail about Webb’s recent discoveries: https://webbtelescope.pub/3Yp62P5

The James Webb Space Telescope’s near-infrared image is perfect to observe the star formation among the swirling clouds of gas and dust in NGC 5068. If observed in visible light, the dust would appear opaque.

Hubble witnessed a dwarf galaxy crashing through the Milky Way galaxy’s gaseous halo and living to tell the tale … though a bit worse for wear! https://bit.ly/3YCVcUE

When the James Webb Space Telescope observed the Horsehead Nebula in infrared light earlier this year, it took this sharp image of the top of the horse’s “mane,” a distinctive dust and gas structure.

Can you guess what this interacting galaxy pair is called? (Hint: 🐧 + 🥚)

In May 2024, the James Webb Space Telescope imaged Arp 142—also known as the Penguin and the Egg—in mid-infrared light to capture the cooler and older aspects of this pair: https://bit.ly/3zThc5q

This James Webb Space Telescope image of Supernova 1987A shows the structures created before and after the explosion. The keyhole was formed from ejected material afterward, while the equatorial ring was made from material ejected thousands of years beforehand: https://bit.ly/482PSxW

Many of the young stars in this the James Webb Space Telescope image of NGC 1333 are surrounded by disks of gas and dust, which may eventually produce planetary systems. Our own Sun and planets formed inside a dusty molecular cloud like this 4.6 billion years ago.

In its first few years, the James Webb Space Telescope has studied a variety of exoplanets—distant worlds that orbit stars outside our solar system.

Despite their great distance from us and faintness, Webb’s sharp infrared gaze and top-notch scientific instruments are enabling astronomers to learn more about the atmospheres of these intriguing worlds—from gas giants to rocky exoplanets.

Learn how Webb is advancing exoplanet science, some of the challenges astronomers encounter, and a few of the big questions we’re hoping to answer.

Combining the power of Hubble and the James Webb space telescopes, astronomers revisited the giant “pancake” of dust encircling the hot young star Vega. Surprisingly, the disk is very smooth, without evidence of large, forming planets: https://bit.ly/4htEAqR

No mask, no veins, no blood … In this new, crisp image from the James Webb Space Telescope and Hubble, the smaller galaxy at left “slithered” behind the larger galaxy. The combo of mid-infrared, visible, and ultraviolet light allows us to see the galaxies in ghastly detail: https://webbtelescope.pub/48wDgQc

The James Webb Space Telescope's Near-Infrared Imager and Slitless Spectrograph (NIRISS) has the unique ability to capture images of bright objects at a resolution greater than the other imagers, using a technique known as aperture mask interferometry: https://webbtelescope.pub/3YZBqV6

Mountains on a moonlit evening? Even better: a gigantic, gaseous cavity in space teeming with star formation known as the Cosmic Cliffs. This James Webb Space Telescope view combines near- and mid-infrared light, which is why the scene may look familiar: https://webbtelescope.pub/3IWlkS0

This three-armed spiral galaxy sits 100 million light-years away in the constellation Leo Minor. In a more zoomed-out image, you would see other galaxies nearby, one close enough to slightly interact with NGC 3430. Credit: ESA/Hubble and NASA.
