NASA's Hubble Space Telescope snaps spooky image of a dying star

The Hubble Space Telescope is sending some seriously spooky Halloween vibes out into the universe with an eerie image of dying star CW Leonis. The star looks like a cosmic cobweb, though there's a very grounded science explanation for its appearance. In keeping with the season, NASA likened the star to a hypnotizing vortex, a peek into a witch's cauldron and a giant space-spider web.  

CW Leonis is what's known as a "carbon star." "The orange-red 'cobwebs' are dusty clouds of sooty carbon engulfing the dying star," the European Space Agency said in a statement on Thursday. "They were created from the outer layers of CW Leonis being thrown out into the inky black void."  Hubble is a joint project of NASA and ESA.  

CW Leonis is located about 400 light-years from Earth, making it our closest carbon star. Hubble has witnessed changes in the material around the star as seen in an animated view of telescope observations between 2001 and 2016.

The cause of the carbon star's shifts in brightness over a relatively short span of time is still under investigation. "Astronomers speculate that gaps in the dust shrouding CW Leonis may allow beams of starlight to pierce through and illuminate dust, like searchlight beacons through a cloudy sky," ESA said.

Hubble's vision is a perfect companion for a Spitzer Space Telescope view of a Godzilla-like nebula that also came out this week. These celestial visual treats are a delightful way to mark Halloween.

NASA's James Webb Space Telescope: Here's What You'll See in the First Images

NASA's James Webb Space Telescope: Here's What You'll See in the First Images

NASA, along with the European and Canadian space agencies, will be releasing the first science images from the brand new James Webb Space Telescope on Tuesday, and now we know what celestial bodies we'll be seeing in those historic pictures.

JWST is the long-awaited successor to the Hubble Space Telescope that finally launched on Christmas Day after years of delays. 

On Friday, NASA revealed the list of cosmic objects that JWST will target for its first batch of full-color images offering unprecedented and detailed views of deep space. If the telescope's stunning first test image is any indication, it's going to be as good as any Instagram feed out there. 

The targets include the Carina Nebula and Southern Ring Nebula, which are bright areas of gas and other material. The Carina Nebula (pictured above) is a so-called stellar nursery where stars are forming, and it's filled with massive stars that help make it one of the largest and brightest nebulas in the sky. The Southern Ring Nebula is a planetary nebula -- in this case, a wide cloud of gas half a light-year in diameter surrounding a dying star -- and relatively close on a cosmic scale, at just 2,000 light-years away.

The southern ring nebula is also known as the "Eight-Burst" Nebula because of it appears to be a figure-8 when seen through some telescopes.

Two other targets we'll see in fantastic high resolution next week are the galaxy group Stephan's Quintet, a particularly photogenic grouping of galaxies that seem to be dancing around each other for eternity, and SMACS 0723, which is a massive galaxy cluster that can act as a so-called gravitational lens to help scientists see deeper into space and observe fainter galaxies.

This quintet of galaxies is made up of four galaxies that are actually near each other and a fifth that appears nearby but is really in the foreground and much closer to Earth.

JWST also is taking a look at the planet WASP-96b, a gas giant world about half the mass of Jupiter and located 1,150 light-years from Earth. The powerful new instruments on the space telescope should be able to provide new insights into the composition of the planet's atmosphere and a fun teaser of what we'll soon discover about other exoplanets, including those that are more Earth-like. 

The images that the space agencies will unveil on July 12 are just the beginning. Scientists have applied to use the telescope through a competitive process, and the first year of observations have already been scheduled. It's quite likely that JWST will change our perspective on some aspects of the universe in the months and years to come.

Hubble captures haunting Ghost Nebula for Halloween

The Skull and Crossbones Nebula has some competition when it comes to creepy space apparitions. 

NASA and the European Space Agency are getting in the Halloween mood with a fresh Hubble Space Telescope look at IC 63, a wispy nebula known as the ghost of Cassiopeia.

The Ghost Nebula haunts the constellation Cassiopeia.

The Ghost Nebula is located in the "W"-shaped constellation Cassiopeia. It's easy to see how it earned its spooky nickname thanks to what NASA poetically calls its "flowing veils of gas and dust." 

"The nebula is being blasted by a torrent of radiation from a nearby, blue-giant star called Gamma Cassiopeiae, which can be easily seen with the unaided eye at the center of the distinctive 'W' asterism that forms the constellation," says NASA.

ESA says the star's ultraviolet radiation bombardment is causing the nebula to slowly dissipate, which only adds to its ghostly mystique. This is possibly the most detailed image ever taken of IC 63, the agency notes, and highlights Hubble's impressive imaging abilities.

Hubble ran into a technical problem with its gyroscopes recently, but a recovery procedure seems to have the telescope close to resuming normal science operations.

Phantom Galaxy Dazzles in Stunning Image From Webb and Hubble Telescopes

Phantom Galaxy Dazzles in Stunning Image From Webb and Hubble Telescopes

It's the buddy flick space fans have been waiting for. The new James Webb Space Telescope and the venerable workhorse Hubble Space Telescope team up to seek out the heart of the Phantom Galaxy. Hijinks ensue. 

The European Space Agency shared a combined telescope view of the Phantom Galaxy in a stunning image released on Monday. Found 32 million light-years away in the Pisces constellation, the galaxy (also known as Messier 74 or M74) is a cover model among spiral galaxies. It's known for its well-defined curving arms, which star in an image that brings together Webb's infrared vision and Hubble's ultraviolet and visible wavelengths.

Three versions of the Phantom Galaxy show Hubble's optical view, the combined image and Webb's infrared view.

ESA showed what the JWST and Hubble images look like separately and what can be learned by mixing the two. "The addition of crystal-clear Webb observations at longer wavelengths will allow astronomers to pinpoint star-forming regions in the galaxies, accurately measure the masses and ages of star clusters, and gain insights into the nature of the small grains of dust drifting in interstellar space," the space agency said.

The colors in the tag-team image highlight different features of the galaxy. Red is dust in the spiral arms, with more orangey areas indicating hotter dust. Young stars glitter in blue. Older stars near the center shine in green and cyan, creating the galaxy's "spooky glow." The pink hot spots are places of star formation.

We saw a preview of Webb's look at the Phantom Galaxy back in July when astronomers got their hands on early Webb datasets and played around with processing and sharing the photogenic scene.

Hubble is a joint project of NASA and ESA, while Webb is run by NASA, ESA and the Canadian Space Agency. The agencies have long said Webb isn't meant as a replacement for Hubble, which is over 30 years old -- pretty ancient in space telescope terms. The two telescopes have different specialties and Hubble could continue to operate into the late 2020s. 

I like to think of Hubble and JWST as the Men in Black of the cosmos, a crusty veteran and a newcomer, both with an interest in space, coming together to make the world of science a better place.
