NASA releases stunning space photos to mark Hubble anniversary

Yahoo24-04-2025
On April 24, 1990, all 24,000 pounds of the Hubble Space Telescope were tucked away inside the Discovery space shuttle when it launched into space. Thirty-five years later, NASA says Hubble has proven to have "opened a new window to the universe," with more than 1.6 million observations to date filled with compelling and surprising images of galaxies, planets and our own solar system.
To celebrate the anniversary milestone, NASA has released stunning photos taken by the telescope in its decades among the stars.
Among them is an image of Mars, taken 61 million miles from Earth.
"Thin water-ice clouds, revealed by Hubble's unique ultraviolet capability, give the Red Planet a frosty appearance," Hubble said along with the photo on social media.
In a news release commemorating Hubble's decades around the sun, NASA said the telescope "is a glowing success story of America's technological prowess, unyielding scientific curiosity, and a reiteration of our nation's pioneering spirit."
"Its stunning imagery inspired people across the globe, and the data behind those images revealed surprises about everything from early galaxies to planets in our own solar system," said Shawn Domagal-Goldman, acting director of the Astrophysics Division at NASA Headquarters in Washington. "The fact that it is still operating today is a testament to the value of our flagship observatories, and provides critical lessons for the Habitable Worlds Observatory, which we plan to be serviceable in the spirit of Hubble."
Another image captured by Hubble shows the nebula NGC 2899, which NASA's Hubble account on X described as being "sculpted by the outflow of radiation and stellar winds from a 40,000-degree-Fahrenheit dying star at its center."
Hubble has looked at roughly 55,000 astronomical targets during its time in space, resulting in over 22,000 scientific papers as of February. Aside from the James Webb Space Telescope, it has contributed to the biggest dataset for a NASA astrophysics mission, with over 400 terabytes of data. Among the observations it has captured are planetary seasons, black hole jets traveling at nearly the speed of light, stellar convulsions, asteroid collisions and expanding supernova bubbles.
One of those observations, a portion of the star-forming Rosette Nebula, shows dark clouds of hydrogen gas laced with dust.
Hubble's ability to capture the cosmos isn't just visually stunning, but has provided numerous scientific breakthroughs. Before the telescope's launch, telescopes grounded on Earth couldn't see as far into space, limiting estimates for the age of the universe and knowledge of space in general. Hubble was able to capture deep field images that showed galaxies dating back to the early universe, allowing scientists to precisely measure the universe's expansion.
Using the telescope, scientists were also able to determine that supermassive black holes are common among galaxies and measure the atmospheres of exoplanets — and it even contributed to the discovery of dark energy.

Map Reveals 'Accelerating' Water Loss Affecting 40 Million Americans

Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. The Colorado River Basin has seen an extensive loss of groundwater loss over two decades, with more than half of the loss being in Arizona, according to a new map drawn from NASA satellite data. Analysis by Arizona State University (ASU) researchers has revealed "rapid and accelerating" groundwater loss in the basin's underground aquifers between 2002 and 2024. Some 40 million Americans rely on water from these aquifers, including in parts of Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming. The team has warned that "climate change is causing more frequent and intense droughts around the world, including in the Colorado River Basin—which supplies water to seven U.S. states and Mexico—and is facing severe water shortages." The basin lost 27.8 million acre-feet of groundwater over the past two decades, which is roughly equal to the storage capacity of Lake Mead, according to paper author and ASU geoscientist Karem Abdelmohsen. Around 68 percent of the losses occurred in the lower part of the basin, which lies mostly in Arizona. Drag slider compare photos "Lots of attention has gone to low water levels in reservoirs over the years, but the depletion of groundwater far outpaces the surface water losses. This is a big warning flag," said Abdelmohsen in a statement. During the first decade of the study period between 2002 and 2014, parts of the basin in western Arizona (in the La Paz and Mohave counties) and in the southeast of the state (Cochise County) lost groundwater at a rate of around 0.2 inches per year. However, this rate more than doubled, to 0.5 inches per year, in the following decade. Scientists say the acceleration of the groundwater loss is likely down to two factors, including the arrival of a "triple-dip" La Niña between 2020 and 2023. (La Niña is an oceanic phenomenon that sees cooler than normal sea-surface temperatures in the central and eastern tropical Pacific Ocean. La Niña typically leads to reduced rainfall over the Southwest and slows the replenishment of aquifers, NASA explained. A "triple dip" is when we get three consecutive years of La Niña conditions.) A second factor at play may be an increase in the amount of groundwater used for agriculture. Arizona saw a rise in agricultural activity in 2014, when large alfalfa farms arrived in La Paz and other southern parts of the state. Dairies and orchards as well as other popular "thirsty" crops grown in the state, such as cotton, corn, and pecans, likely impacted groundwater supplies, Famiglietti said. According to data from the Arizona Department of Water Resources, 72 percent of the state's available water supply is used for irrigated agriculture. Many farms use "vast" amounts of groundwater, Famiglietti said, partly because they use flood irrigation, where water is released into trenches that run through crop fields. The long-standing practice, commonly used for alfalfa and cotton, tends to be the cheapest option but can lead to more water loss and evaporation than other irrigation techniques, such as overhead sprinklers or dripping water from plastic tubing. The latest study also found evidence that managing groundwater can help keep Arizona aquifers healthier. For example, the active management areas and irrigation non-expansion areas formed as part of the Arizona Groundwater Management Act of 1980 cut down water losses in some areas. The designation of a new active management area in the Willcox Groundwater Basin is also likely to further slow groundwater losses. "Still, the bottom line is that the losses to groundwater were huge," Abdelmohsen said. Do you have a tip on a science story that Newsweek should be covering?

NASA Confirms A ‘Betel-Buddy' Is Orbiting Supergiant Star Betelgeuse

Astronomers have discovered a companion star in an incredibly tight orbit around Betelgeuse, using ... More the NASA-NSF-funded 'Alopeke instrument on the Gemini North telescope. Betelgeuse, one of the most famous stars in the night sky, has a close companion, and that may explain why it dimmed dramatically in 2019-20. About 640 light-years from the solar system, red supergiant star Betelgeuse in the constellation Orion is famous not only for its unmistakable color, but also because it's one of the closest stars that could soon explode as a supernova. Betelguese And Its 'Great Dimming' Approximately 700 times larger than the sun, Betelgeuse has puzzled astronomers for years because it waxes and wanes in brightness every six years, with its recent 'Great Dimming' event ultimately attributed to a dust cloud ejected by the star. Scientists suspected it may have been caused by a companion star, but failed to detect it using NASA's Hubble Space Telescope or the Chandra X-ray Observatory. Now it's been found, after a team of astrophysicists led by Steve Howell, a senior research scientist at NASA Ames Research Center, has pointed the Gemini North Telescope in Hawaii at Betelgeuse. The team's findings were published today in The Astrophysical Journal Letters. The location of Betelgeuse, at the top-left corber of the Orion constellation. How 'Betel-Buddy' Was Found Using the telescope's Alopeke speckle imager — which takes high-resolution short exposures to minimize the blurring effects of Earth's atmosphere — the companion star was found. Six magnitudes dimmer than Betelgeuse, the young, blue-white star orbits Betelgeuse from just four times the Earth-sun distance. That's well within the red supergiant star's outer atmosphere. The Alopeke imager was decisive. 'Gemini North's ability to obtain high angular resolutions and sharp contrasts allowed the companion of Betelgeuse to be directly detected,' said Howell. 'Papers that predicted Betelgeuse's companion believed that no one would likely ever be able to image it.' Gemini North, one half of the International Gemini Observatory, supported in part by the U.S. ... More National Science Foundation and operated by NSF NOIRLab. Why Betelgeuse Is Special Betelgeuse is a special star. It's the archetype of a red supergiant star near the end of its life cycle, during which its outer atmosphere is expanding. This is the first direct observation of a companion star orbiting within the outer atmosphere of a supergiant. It's thought that the companion may spiral inward and be consumed by Betelgeuse within the next 10,000 years. Astronomers are already preparing for November 2027, when the companion will be at its maximum separation from Betelgeuse, offering the best chance yet for further observation and analysis. Wishing you clear skies and wide eyes.

Scientists Just Witnessed the Birth of a Solar System for the First Time

"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." Here's what you'll learn when you read this story: Observations of the young HOPS-315 star system show an environment analogous to what our own nascent Solar System would have looked like billions of years ago. The star is surrounded by a protoplanetary disk, and this disk is the first evidence of debris condensing into what will eventually become planets and other objects. Observing this early phase of evolution around a protostar will allow scientists to learn more about the formation of our own Solar System. If our Solar System had baby pictures from over 4.5 billion years ago, they would look something like the otherworldly swirls of dust and gas surrounding the young star HOPS-315. Nascent planets forming around young stars have been observed before, but until now, what hasn't been seen is the phase of star system formation before that, when mineral particles condense at extreme temperatures from a protoplanetary disk to form what will later become those new planets. The enormous surrounding clouds of gas and dust tend to obscure what was going on. But NASA's James Webb Space Telescope (by making observations at infrared and millimeter wavelengths) has finally revealed chemical signals that are, for a star system, what ultrasound images are for human pregnancies. The sources for these signals were crystalline minerals floating in hot silicon monoxide (SiO) gas in the inner region of the protoplanetary disk around HOPS-315. The star and its disk are located 1,300 light-years away, which means we are seeing them as they existed during humanity's year 700. And because a thousand years is a blink of an eye in cosmic terms, HOPS-315 is probably still a developing protostar. When an international team of researchers found out about the Webb observations, they zeroed in with ESO's Atacama Large Millimeter Array (ALMA) and captured the moment that minerals (which had sublimated in the intense heat, meaning that they evaporated without turning liquid) started to condense into planetary embryos. 'The first high-temperature minerals to recondense from this gaseous reservoir start the clock on planet formation,' said the team (led by astronomer Melissa McClure of Leiden University in the Netherlands) in a study recently published in the journal Nature. This is what McClure goes on to call a 't=0 moment' in the creation of a new planetary system. When she and her team compared their findings with models of how our Solar System came into being, they found that the formation of solids from cooling gases and mineral dust in the HOPS-315 system mirrored what is thought to have happened in our own stellar territory. The materials that form from the early phases of this process are known as refractory solids, which can survive intense heat without degrading. When our Solar System was forming, the temperature around proto-Earth is thought to have been around 327 degrees Celsius (620 degrees Fahrenheit). Remnants of the first solids that ever condensed in this region of our Solar System can be found embedded in primordial meteorites that have crashed to Earth, taking the form of flecks of minerals. Some of these flecks are even older than the Solar System itself—the presolar grains in the Murchison meteorite, for instance, go back 7 billion years. They are thought to have come from the remains of ancient stars that were swept through the interstellar medium, forming a new nebula that eventually flattened into the protoplanetary disk from which our Solar System emerged. 'Comparison with condensation models with rapid grain growth and disk structure models suggests the formation of refractory solids analogous to those in our Solar System,' McClure said. And if the HOPS-315 system continues to evolve as our own system did, minerals will collide and stick to each other until they form larger and larger rocks, which will accrete into planetesimals and, eventually, actual planets. We'll just have to keep watching and learning. You Might Also Like The Do's and Don'ts of Using Painter's Tape The Best Portable BBQ Grills for Cooking Anywhere Can a Smart Watch Prolong Your Life?
