Here’s another striking image from the venerable Hubble Space Telescope. These billows of blue and red show a detailed look at a small portion of the famous Orion Nebula. But what really catches the eye are the brilliant stars with the cross-shaped diffraction spikes — a hallmark of Hubble images.Continue reading “Beautiful New Hubble Photo Shows Hot, Young Variable Stars in the Orion Nebula”
The ancients didn’t have the scientific understanding of nature that we have now. All they could do was look up at the night sky and wonder, which isn’t a bad way to spend time. Part of understanding something is naming it, and when the ancients looked up at the patterns in the stars, they gave them simple names based entirely on their appearances. That’s likely how the Greeks named the constellation Serpens: it looks like a snake, so they called it that.
The Greeks lacked astronomical telescopes, so they never saw any of the rich detail in Serpens that a new image from the European Southern Observatory reveals.Continue reading “This Serpent’s Tail is Made of Starry Nebulae”

Like a famous (and photogenic) actor followed by paparazzi, the Carina Nebula is one of the most photographed objects in space because of its stunning beauty. Over the years, the Carina Nebula has been one of the Hubble Space Telescope’s most-imaged objects.Continue reading “Here's a new Image of the Carina Nebula From Hubble”
Two thousand five hundred years ago, during the height of the bronze age, an old red star died. Its outer layers expanded over time, becoming what is now known as the Southern Ring Nebula, or less romantically, NGC 3132. By the looks of it, this planetary nebula looks like many others. As Sun-like stars die, they swell to become red giants before becoming a white dwarf, and their outer layers typically become a planetary nebula. But a recent study finds that this particular nebula formed in a way quite messier than we had thought.Continue reading “The Formation of the Southern Ring Nebula was Messier Than the Death of a Single Star”
Here’s a dramatic and spectacular new view of the Cone Nebula, as seen by the Very Large Telescope (VLT). This nebula is part of a distant star-forming region called NGC 2264, which about 2,500 light-years away. Its pillar-like appearance is a perfect example of the shapes that can develop in giant clouds of cold molecular gas and dust, known for creating new stars.Continue reading “A New View of the Cone Nebula From the Very Large Telescope”
In a recent study published in Monthly Notices of the Royal Astronomical Society, an international team of researchers led by Stanford University have produced the first computer-generated 3D model of the Cat’s Eye Nebula, which unveiled a symmetric pair of rings that enclose the outer shell of the nebula. This study holds the potential for helping us better understanding the nebula’s makeup and how it formed, as the symmetric rings provides clues that they were formed from a precessing jet, which produces strong confirmation that a binary star exists at the nebula’s center.Continue reading “Astronomers Simulate the Cat’s Eye Nebula in 3D”
This is it, folks. Feast your eyes! It’s what we’ve been training for—seeing the James Webb Space Telescope’s first detailed view of the Orion Nebula! JWST’s NIRCam gazed at this starbirth nursery and revealed incredible details hidden from view by gas and dust clouds.Continue reading “The Webb Image you’ve Been Waiting For: the Orion Nebula”
Here’s the Tarantula Nebula like we’ve never seen it before. The James Webb Space Telescope turned its detectors towards the Large Magellanic Cloud about 161,000 lightyears away to take a look at 30 Doradus, more commonly known as the Tarantula Nebula. JWST’s exceptional infrared view has now revealed thousands of never-before-seen young stars in this stellar nursery, as well incredible views of the wispy, dusty filaments and the impressive collection of massive older stars.
There is so much detail in this image, if you download the full-sized version, you can pan and zoom around to see details on stars and the surrounding dust and gas. And there are even other, more distant galaxies dotting the background. If you have a big screen, even better, as it takes up over 14,000 x 8,000 pixels. Or, take a look at the video tour, below.Continue reading “Wow! Here's Webb's View of the Tarantula Nebula”
The Orion Nebula is a giant cloud of gas and dust that spans more than 20,000 times the size of our own solar system. It one of the closest active star-forming regions to Earth, and is therefore one of the most observed and photographed objects in the night sky. The venerable Hubble Space Telescope has focused on the Orion Nebula many times, peering into giant cavities in the hazy gas, and at one point, Hubble took 520 images to create a giant mosaic of this spellbinding nebula.
Now, Hubble has captured new views of a wispy, colorful region in the Orion Nebula surrounding the Herbig-Haro object HH 505.Continue reading “Brand New Stars in the Orion Nebula, Seen by Hubble”
Ever wonder what it would be like to fly through the Orion Nebula with all its newborn stars? Or buzz through the California Nebula? Of course, we’ve seen simulated “fly-throughs” of nebulae in sci-fi TV and movies and on planetarium domes. But, what if we had a warp-speed spaceship and could chart a path through the real thing? The first thing we’d need is accurate data about that region of space. That’s where a 3D model with precise distance measurements to stars and other objects would come in really handy.Continue reading “Thanks to Gaia, Astronomers are Able to Map Out Nebulae in 3D”
