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 […]
NASA Warns of “Invisible Monster On the Loose” Traveling at High Speed Through Space
There’s an invisible monster on the loose, barreling through intergalactic space so fast that if it were in our solar system, it could travel from Earth to the Moon in 14 minutes. This supermassive black hole, weighing as much as 20 million Suns, has left behind a never-before-seen 200,000-light-year-long “contrail” of newborn stars, twice the […]
Across the Universe: Hubble Ultra Deep Field
The Hubble (Hubble Space Telescope) Ultra Deep Field (HUDF) peers deeper into the universe than any previous visible-light image. Multiple observations of the same small patch of sky were combined for an equivalent exposure time of more than 11 days. Revealed within the image are thousands of galaxies located many billions of light-years away. Many […]
Hubble’s Messier Catalog
Even the great observer Charles Messier had trouble seeing this globular cluster when building his Catalog of Nebulae and Star Clusters. It was originally spotted in 1752 by a French astronomer in what is now South Africa, but it took until 1778 for Messier to catalog it. This is because, while Messier 55 is large […]
