NASA's Webb Telescope captured a near-infrared image of the Sombrero galaxy, highlighting its bright central bulge while revealing less of the dust disk due to infrared light's ability to pass through dust.
Observing the galaxy in visible (Hubble), near-IR, and mid-IR (Webb) helps astronomers study how stars, dust, and gas interact and evolve over time.
The mid-infrared image shows the galaxy's dust glowing, while in near-infrared, stars shine through more clearly, making the dust less pronounced.
Located 30 million light-years away, the Sombrero galaxy is seen nearly edge-on and has a mass equivalent to about 800 billion Suns.
Variations in the chemical makeup of its 2,000+ globular clusters suggest the galaxy may have merged with another galaxy in the past.
A noticeable warp in the inner disk, visible due to our slightly tilted viewing angle, supports the idea of a past galactic merger.
Webb's powerful resolution reveals red giant stars and a colorful array of distant background galaxies, offering more clues about stellar evolution and cosmic structure.

Musk could lose billions of dollars depending on how spat with Trump unfolds
NEW YORK: The world's richest man could lose billions in his fight with world's most powerful politician. The feud between Elon Musk and Donald Trump could mean Tesla's plans for self-driving cars hit a roadblock, SpaceX flies fewer missions for NASA, Starlink gets fewer overseas satellite contracts and the social media platform X loses advertisers. Maybe, that is. It all depends on Trump's appetite for revenge and how the dispute unfolds. Joked Telemetry Insight auto analyst Sam Abuelsamid, 'Since Trump has no history of retaliating against perceived adversaries, he'll probably just let this pass.' Turning serious, he sees trouble ahead for Musk. 'For someone that rants so much about government pork, all of Elon's businesses are extremely dependent on government largesse, which makes him vulnerable.' Trump and the federal government also stand to lose from a long-running dispute, but not as much as Musk. Tesla robotaxis The dispute comes just a week before a planned test of Tesla's driverless taxis in Austin, Texas, a major event for the company because sales of its EVs are lagging in many markets, and Musk needs a win. Trump can mess things up for Tesla by encouraging federal safety regulators to step in at any sign of trouble for the robotaxis. Even before the war of words broke out on Thursday, the National Highway Transportation Safety Administration requested data on how Musk's driverless, autonomous taxis will perform in low-visibility conditions. That request follows an investigation last year into 2.4 million Teslas equipped with full self-driving software after several accidents, including one that killed a pedestrian.

June offers skywatchers worldwide rare views of the Milky Way's illuminated heart; Here is how to spot it with naked eyes
TIL Creatives June 2025 presents a unique chance for skywatchers to see the Milky Way's bright central bulge, best viewed throughout the month. This celestial display offers a hazy band in the sky from sunset to dawn, ideal for long-exposure photography. June 2025 offers a remarkable opportunity for skywatchers to observe the Milky Way's luminous central bulge, visible throughout the month. This celestial event, highlighted by NASA's June Skywatching Tips, is best experienced from dark, remote locations away from city lights. The Milky Way's core becomes visible from sunset to dawn, appearing as a faint, hazy band stretching across the sky. This central region, rich in stars, gas, and dust, creates a distinct cloud-like structure observable to the naked eye. Long-exposure photography can reveal intricate details, showcasing the galaxy's star clusters and dark dust position relative to the Milky Way during June allows for a direct view toward the galaxy's dense center. This alignment provides an exceptional chance to witness the Milky Way's core, a phenomenon visible all month. June's night sky also features notable planetary alignments. Venus shines brightly before sunrise, while Saturn rises higher each day. On June 16 and 17, Mars will appear close to Regulus, the brightest star in the Leo constellation, separated by only about half a degree, the width of the full moon. This rare conjunction is ideal for observation with binoculars or small telescopes. The June solstice occurs on June 20 (June 21 UTC), marking the longest day of the year in the Northern Hemisphere. This event results from Earth's axial tilt, positioning the North Pole closest to the Sun. Ancient cultures have historically aligned monuments with the solstice, underscoring its significance. For optimal viewing of the Milky Way's core and other celestial events, observers should seek locations with minimal light pollution and clear skies. The new moon on June 25 will provide darker skies, enhancing visibility of faint celestial 2025 presents an unparalleled opportunity to connect with the cosmos. It offers a series of celestial events that promise to captivate both amateur and seasoned June, the Milky Way's core is visible from most places around the world, but how well you see it depends on your location, the time of night, and light pollution. Northern Hemisphere:You can see the Milky Way's core low on the southern horizon, especially after midnight in mid to late June. Southern Hemisphere: This is the best place to see it. The core rises higher in the sky, making it brighter and more detailed to the naked eye or through long-exposure photography. Around midnight to early morning (between 11 PM and 4 AM). Around the new moon (June 25, 2025), when skies are darker. Get away from city lights (light pollution blocks it). Look toward the south and southeast sky. Use a star map or app to track the galactic center.

This volcano on Mars is taller than Earth's Mount Everest
NASA's 2001 Mars Odyssey orbiter has delivered a stunning new picture from Mars, capturing the colossal Arsia Mons volcano piercing through a dense layer of early morning panorama, taken on May 2, marks the first time one of the planet's massive volcanoes has been imaged on the Martian horizon — a view reminiscent of how astronauts see Earth's mountains from the International Space Mons, the southernmost of the Tharsis Montes trio, stands at an awe-inspiring 12 miles (20 kilometers) high, dwarfing Earth's tallest volcano, Mauna Loa, which rises 6 miles (9 kilometers) above the seafloor. Arsia Mons, an ancient Martian volcano, was captured before dawn on May 2, 2025, by NASA's 2001 Mars Odyssey orbiter. (Photo: Nasa) The volcano's summit was seen poking above a canopy of water ice clouds, a phenomenon common in the region during Mars' aphelion, when the planet is farthest from the Sun. This period creates the 'aphelion cloud belt,' a striking band of clouds that forms across the Martian equator and is prominently displayed in Odyssey's new Odyssey spacecraft, launched in 2001, is the longest-running mission orbiting another planet. To capture this unique image, the orbiter rotated 90 degrees, allowing its Thermal Emission Imaging System (THEMIS) camera—designed to study the Martian surface—to photograph the horizon innovative angle enables scientists to observe layers of dust and water ice clouds, as well as seasonal changes in the Martian atmosphere. Arsia Mons is the southernmost of the three volcanoes that make up Tharsis Montes, shown in the center of this cropped topographic map of Mars. (Photo: Nasa) 'We're seeing some really significant seasonal differences in these horizon images,' said Michael D. Smith, planetary scientist at NASA's Goddard Space Flight Center. 'It's giving us new clues to how Mars' atmosphere evolves over time'.Understanding these clouds is crucial for predicting Martian weather and preparing for future missions, including safe landings. Arsia Mons itself is not only a geological marvel—measuring 270 miles (450 kilometers) in diameter—but also a key to understanding Mars' atmospheric Hill, operations lead for Odyssey's THEMIS camera, summed up the excitement: 'We picked Arsia Mons hoping we would see the summit poke above the early morning clouds. And it didn't disappoint'.
