Astronomers have used #NASAWebb—most powerful infrared telescope to date—to search for brown dwarfs at very low masses in a nearby nebula that contains newborn stars. Join Dr. Kevin Luhman (Penn State) for a discussion on the surprising aspect of these new brown dwarfs on Feb. 24, at 7 p.m. ET. 🔭

How are stars born? ✨ With the James Webb Space Telescope, astronomers are peering more deeply into star-forming regions than ever before to reveal the nuances of the processes.

In case you missed it: This visualization examines the Hubble Space Telescope image of the Egg Nebula, released last week. Travel around the nebula in three dimensions! The dying star has repeatedly ejected thin shells of gas and dust over the last 5,000 years.

These galaxies are “dancing” and “twirling,” and will ultimately merge. Irregular features like long tails, asymmetrical structures, and two bright cores are telltale signs of galaxy mergers. NGC 3256 was observed by Hubble and is 100 million light-years away. Credit: ESA, NASA.

Every day we get to work on the amazing Hubble, James Webb and upcoming Nancy Grace Roman space telescopes. We have to admit, they're out of this world! 😁 🔭 Happy Valentine's Day to our favorite NASA missions. 🫶

This celestial firestorm is the blazing wreckage of a collision between two spiral galaxies. The Antennae Galaxies show off two long streamers of stars, gas, and dust that extend from the crash site.

If you've ever wondered what Hubble and Webb were observing at any time, there's an easy way to find out! 👀 Space Telescope Live can show you what the telescopes are looking at now and what the next planned observation will be, all in one space (pun intended 😁): https://spacetelescopelive.org/

It’s a continuous cycle: space telescope technology 🔁 astronomical observations. As we learn about the universe with space telescopes, like #Hubble and #NASAWebb, investigating ongoing mysteries and answering new questions requires state-of-the-art technology. Credit: STScI.
