Hubble Celebrates 35th Year in Orbit
Astronomers knew that placing a telescope above Earth’s blurry atmosphere would allow for them to behold the Universe like never before. Hubble’s view would be ten times sharper than conventional ground-based telescopes of the time. Its high sensitivity would uncover objects more than one-billionth the brightness of the faintest stars seen by the human eye. […]
Hubble Investigates Galaxy with Nine Rings
NASA’s Hubble Space Telescope has captured a cosmic bullseye! The gargantuan galaxy LEDA 1313424 is rippling with nine star-filled rings after an “arrow” — a far smaller blue dwarf galaxy — shot through its heart. Astronomers using Hubble identified eight visible rings, more than previously detected by any telescope in any galaxy, and confirmed a […]
Found: First Actively Forming Galaxy as Lightweight as Young Milky Way
“I didn’t think it would be possible to resolve a galaxy that existed so early in the Universe into so many distinct components, let alone find that its mass is similar to our own galaxy’s when it was in the process of forming,” said Lamiya Mowla, co-lead author of the paper and an assistant professor […]
Jupiter’s Great Red Spot Behaves Like a Stress Ball
Astronomers have observed Jupiter’s legendary Great Red Spot (GRS), an anticyclone large enough to swallow Earth, for at least 150 years. But there are always new surprises – especially when NASA’s Hubble Space Telescope takes a close-up look at it. Hubble’s new observations of the famous red storm, collected 90 days between December 2023 to […]
Mystery of Missing Water from Mars Solved
Mars was once a very wet planet as is evident in its surface geological features. Scientists know that over the last 3 billion years, at least some water went deep underground, but what happened to the rest? Now, NASA’s Hubble Space Telescope and MAVEN (Mars Atmosphere and Volatile Evolution) mission are helping unlock that mystery. […]
Pillars of Creation Star in New Visualization
Made famous in 1995 by NASA’s Hubble Space Telescope, the Pillars of Creation in the heart of the Eagle Nebula have captured imaginations worldwide with their arresting, ethereal beauty. Now, NASA has released a new 3D visualization of these towering celestial structures using data from NASA’s Hubble and James Webb space telescopes. This is the […]
Tracing the Growth of Galaxies
Like documenting a child’s development in a scrapbook, astronomers use Hubble to capture the appearance of many developing galaxies throughout cosmic time. This is possible because of the mathematical relationship between cosmic distance and time: the deeper Hubble peers into space, the farther back it looks in time. This occurs because light travels at a […]
NASA Hubble Observes How an Exoplanet’s Atmosphere Changes (Video)
By combining several years of observations from NASA’s Hubble Space Telescope along with conducting computer modelling, astronomers have found evidence for massive cyclones and other dynamic weather activity swirling on a hot, Jupiter-sized planet 880 light-years away. The planet, called WASP-121 b, is not habitable. But this result is an important early step in studying […]
Webb, Hubble Combine to Create Most Colourful View of Universe (Video)
The result: a vivid landscape of galaxies along with more than a dozen newly found time-varying objects This panchromatic view of galaxy cluster MACS0416 was created by combining infrared observations from the NASA/ESA/CSA James Webb Space Telescope with visible-light data from the NASA/ESA Hubble Space Telescope. To make the image, in general the shortest wavelengths […]
Hubble Finds Bizarre Explosion in Unexpected Place
Luminous Fast Blue Optical Transients (LFBOT) are among the brightest known visible-light events in the universe – going off unexpectedly like camera flashbulbs. Only a handful have been found since the first discovery in 2018. Presently, LFBOTS are detected about once per year. After its initial detection, the latest LFBOT was observed by multiple telescopes […]
