Using Webb, researchers have confirmed the presence of planet-forming disks in NGC 346, and discovered that these disks are long-lived. The finding is causing scientists to rethink current models of planet formation.
Like fireflies “dancing” on a warm summer night, 10 distinct star clusters appear in observations from NASA’s James Webb Space Telescope. They are held in a cocoon of diffuse light emitted by other stars scattered around them. This galaxy, known as Firefly Sparkle, was taking shape around 600 million years after the big bang.
For a decade, Hubble's OPAL program has kept an eye on our solar system's outer planets, making global studies of their cloud coloration, activity, and atmospheric motion to understand the underlying mechanics of their weather and climate systems.
Astronomers have used Hubble to see closer than ever into an energetic monster black hole powering 3C 273, the first quasar ever discovered. The new image details a lot of weird things: filaments, lobes, and a mysterious L-shaped structure, all within 16,000 light-years of the black hole.
There’s somewhat of an inside joke in the astronomical community that researchers aren’t the best at naming things. For example, the first star observed by Webb is named HD 84406. Not so catchy. Neither is galaxy cluster MACS0416, a deep field imaged by Webb recently. There are exceptions to this, though. Think the Hourglass Nebula, the Cigar Galaxy, or the Cat’s Paw Nebula. All named for the objects on Earth that they resemble. The Sombrero Galaxy is aptly named for its likeness to the wide-brimmed hat. However, it appears the name is not always accurate, as NASA’s James Webb Space Telescope’s look shows. In the mid-infrared, the 'crown' of the 'hat' is no longer visible, causing the galaxy to take on a much different appearance.
Young star FU Orionis is pretty shocking! Astronomers used the Hubble Space Telescope 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.
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!
Combining the power of the Hubble and James Webb space telescopes, astronomers revisited the legendary star Vega and found a smooth disk surrounding it—a surprise to astronomers who expected to see evidence of one or more large planets plowing through the disk, which is common around other young stars. But Vega is forcing astronomers to rethink the range and variety of planetary systems around stars.
This ghastly galactic “countenance” recalls mythological human-hunters like the Algonquian wendigo — an emaciated figure with ashen flesh and glowing eyes that grows larger and larger as it feasts, and is never satiated.
The Hubble Space Telescope has provided a dramatic and colorful close-up look at R Aquarii, one of the most rambunctious stars in our galaxy, weaving a huge spiral pattern among the stars.
Uranus, the planet second most distant from our Sun, has been described as mysterious, strange, and fairly unknown to those of us here on Earth. However, in astronomy, these terms are pretty relative. Compared to the remote, dark stretches of the early universe or oddball exoplanets dozens of light-years from our solar system, researchers actually know a lot about Uranus.
Using Hubble, astronomers have discovered that Jupiter's Great Red Spot (GRS) is not as stable as it might look. Hubble measurements of the GRS's size, shape, brightness, color, and vorticity showed it can change dimensions—looking like a slightly skinnier or fatter red oval over 90 days.
Using NASA’s James Webb Space Telescope, a team of astronomers observed Centaur 29P/Schwassmann-Wachmann 1, one of the most active and intriguing objects in the outer solar system. The high degree of detail captured by the telescope led to the discovery of new, previously unknown jets of gas, which is helping inform theories about how centaurs and planets are formed.
Astronomers using the Hubble Space Telescope have discovered that the blowtorch-like jet blasting from a supermassive black hole at the core of galaxy M87 seems to cause stars to erupt along its trajectory. The stars, called novae, are not caught inside the jet, but are apparently in a dangerous neighborhood nearby. Hubble found twice as many novae going off near the jet as elsewhere in the giant galaxy during the surveyed time period.
Amid a crowded field of galaxies captured by NASA’s James Webb Space Telescope, one otherwise inconspicuous galaxy stands out for emitting a light signature that astronomers have never seen before. Together, an observational astronomer and a theorist investigated potential causes.
Arp 107, a pair of interacting galaxies, shines brightly in high-resolution infrared light. A collision, which occurred hundreds of millions ago, created a tenuous bridge of gas and dust that connects the two galaxies, and started a new wave of star formation that NASA’s James Webb Space Telescope captures clearly.
Using Hubble, astronomers have found more black holes in the early universe than previously thought. They went black hole hunting in the landmark Hubble Ultra Deep Field, first revealed in 2004, and in following observations to look for supermassive black holes.
How do environmental factors affect the star formation process? To help answer this question, NASA’s James Webb Space Telescope examined the fringes of our Milky Way galaxy. Webb’s near- and mid-infrared imaging capabilities enabled scientists to examine a star-forming area reminiscent of our galaxy during its early formation.
Hubble and Chandra have uncovered a pair of supermassive black holes that are just 300 light-years apart. They are buried deep inside the heart of a pair of colliding galaxies that will eventually merge to make a bigger black hole.
A Martian mystery: What happened to the water that once covered the Red Planet? Scientists know some of it went deep underground, but what became of the rest? Hubble and MAVEN teamed up to help scientists understand the history of water on Mars.
