NASA’s Hubble Spies Stellar Sparkler for July 4th
Ancient stars shine in red, white and blue from a globular cluster almost as old as the universe itself in this image from NASA's Hubble Space Telescope. Red, white, and blue stars glitter like a sparkler being waved on a dark night in this new image from NASA’s Hubble Space Telescope. NASA released this image to celebrate the United States’ 250th anniversary, as the agency carries forward America’s legacy of exploration.
NASA’s Hubble Captures Crimson Cloud Sparkling with White, Blue Stars
A glowing landscape of gas and dust is heated and illuminated by a thriving population of young stars in the LH 95 region of the Large Magellanic Cloud. Like fresh fireworks launched against a background of dissipating smoke, blue and white stars shine brilliantly against a crimson background of glowing gas in this image of stellar nursery LH 95 from NASA’s Hubble Space Telescope. LH 95 is a region in the Large Magellanic Cloud, a dwarf galaxy that orbits the Milky Way.
NASA’s Hubble Spots Star-Spangled Cosmic Scene
This image from NASA's Hubble Space Telescope shows Messier 3, a densely packed cluster of stars whose origins may be a merger between globular clusters in the early universe. More than 500,000 stars blaze red, white, and blue in this image from NASA’s Hubble Space Telescope, released in celebration of the United States’ 250th anniversary. The image showcases Messier 3 (M3), one of the Milky Way galaxy’s most massive globular clusters, or spherical collections of gravitationally bound stars.
Stellar Explosions
In 185 A.D., Chinese astronomers noted a “guest star” that appeared in the sky and remained there for eight months. The strange star was perhaps the earliest recorded supernova observation, but humans have been witnessing stellar explosions for as long as they’ve looked to the skies. Long ago, the sudden, temporary brightening of a point of light in the sky made people think that they were seeing new stars.
Pulsars - NASA Science
Pulsars are the lighthouses of the universe. They’re neutron stars ― the very dense remnants of a dead star ― that are highly magnetic and rotate rapidly as they emit beams of radiation, generally from the vicinity of their magnetic poles. As the pulsar spins around on its axis, it sweeps a beam of radiation around the cosmos like a turning lighthouse that shines out into the sea. From Earth, we see the beam as it sweeps rapidly past as a pulse of radiation.
Hubble Snaps Stellar Baby Pictures Original
Newly developing stars shrouded in thick dust get their first baby pictures in these images from NASA’s Hubble Space Telescope. Hubble took these infant star snapshots in an effort to learn how massive stars form. Protostars are shrouded in thick dust that blocks light, but Hubble can detect the near-infrared emission that shines through holes formed by the protostar’s jets of gas and dust.
Hubble Observes Ghostly Cloud Alive with Star Formation
A seemingly serene landscape of gas and dust is hopping with star formation behind the scenes. While this eerie NASA Hubble Space Telescope image may look ghostly, it’s actually full of new life. Lupus 3 is a star-forming cloud about 500 light-years away in the constellation Scorpius. White wisps of gas swirl throughout the region, and in the lower-left corner resides a dark dust cloud.
Hubble's Album of Planet-Forming Disks Original
Hubble images of protoplanetary disks in visible and infrared light show dusty regions around newly developing stars where planets may form. This collection of new images taken by NASA’s Hubble Space Telescope showcases protoplanetary disks, the swirling masses of gas and dust that surround forming stars, in both visible and infrared wavelengths. Through observations of young stellar objects like these, Hubble helps scientists better understand how stars form.
Hubble Observes Stars Flaring to Life in Orion
Just-forming stars, called protostars, dazzle a cloudy landscape in the Orion Molecular Cloud complex (OMC). These three new images from NASA’s Hubble Space Telescope were taken as part of an effort to learn more about the envelopes of gas and dust surrounding the protostars, as well as the outflow cavities where stellar winds and jets from the developing stars have carved away at the surrounding gas and dust.
Hubble Nets Menagerie of Young Stellar Objects
A bright reflection nebula shares the stage with a protostar and planet-forming disk in this Hubble image. A disparate collection of young stellar objects bejewels a cosmic panorama in the star-forming region NGC 1333 in this new image from NASA’s Hubble Space Telescope. To the left, an actively forming star called a protostar casts its glow on the surrounding gas and dust, creating a reflection nebula.
Hubble Spies Stellar Blast Setting Clouds Ablaze Original
Jets of ionized gas streak across a cosmic landscape from a newly forming star. This new NASA Hubble Space Telescope image captures a jet of gas from a forming star shooting across the dark expanse. The bright pink and green patches running diagonally through the image are HH 80/81, a pair of Herbig-Haro (HH) objects previously observed by Hubble in 1995. The patch to the upper left is part of HH 81, and the bottom streak is part of HH 80.
Hubble Constant and Tension
We know that the universe is expanding. Astronomer Edwin Hubble, for whom the Hubble Space Telescope is named, discovered cosmic expansion in 1929, observing that the farther away a galaxy is from Earth, the faster it appears to be receding from us. But a key question remains: what specifically is the relationship between how far away an object is and how fast it recedes from us? We call this value the Hubble Constant.
NASA’s Hubble and Webb Telescopes Reveal Two Faces of a Star Cluster Duo
A riotous expanse of gas, dust, and stars stake out the dazzling territory of a duo of star clusters in this combined image from NASA’s Hubble and Webb space telescopes. Open clusters NGC 460 and NGC 456 reside in the Small Magellanic Cloud, a dwarf galaxy orbiting the Milky Way. Open clusters consist of anywhere from a few dozen to a few thousand young stars loosely bound together by gravity.
Hubble Observations Give “Missing” Globular Cluster Time to Shine
A previously unexplored globular cluster glitters with multicolored stars in this NASA Hubble Space Telescope image. Globular clusters like this one, called ESO 591-12 or Palomar 8, are spherical collections of tens of thousands to millions of stars tightly bound together by gravity. Globular clusters generally form early in the galaxies’ histories in regions rich in gas and dust. Since the stars form from the same cloud of gas as it collapses, they typically hover around the same age.
Hubble and Artificial Intelligence
Huge sets of data pulled in from telescopes and observatories around the world, including the Hubble Space Telescope, provide a treasure trove of information for astronomers seeking to unlock the secrets of the cosmos. But while it would take countless hours for individuals to sort through information from years of observations, artificial intelligence (AI) programs can use pattern recognition to swiftly identify key components for astronomical investigations.
Industrial Partners - NASA Science
Hubble's Industrial and Academic Partners Hubble's success springs from a collaboration between NASA and its industrial partners, who bring their innovation, creativity, and expertise to the telescope's past construction and current operations. Hubble was designed and built through partnerships with companies and universities throughout the United States and around the globe.
Hubble Examines Stars Ensconced in a Cocoon of Gas
An open cluster of stars shines through misty, cocoon-like gas clouds in this Hubble Space Telescope image of NGC 460. NGC 460 is located in a region of the Small Magellanic Cloud, a dwarf galaxy that orbits the Milky Way. This particular region contains a number of young star clusters and nebulae of different sizes ― all likely related to each other.
Hubble Unveils a Glittering View of Sh2-284 Original
A tiny fraction of the stellar nursery known as Sh2-284 is visible in this glittering, star-filled NASA Hubble Space Telescope image. This immense region of gas and dust is the birthing place of stars, which shine among the clouds. Bright clusters of newborn stars glow pink in infrared light, and clouds of gas and dust, resembling puffy cumulus clouds, are dotted with dark knots of denser dust.
Hubble Jams With A Cosmic Guitar Original
Arp 105 is a dazzling ongoing merger between an elliptical galaxy and a spiral galaxy drawn together by gravity, characterized by a long, drawn out tidal tail of stars and gas more than 362,000 light-years long. The immense tail, which extends beyond this image from NASA’s Hubble Space Telescope, was pulled from the two galaxies by their gravitational interactions and is embedded with star clusters and dwarf galaxies.
Hubble Spies a Spectacular Starburst Galaxy
Sweeping spiral arms extend from NGC 4536, littered with bright blue clusters of star formation and red clumps of hydrogen gas shining among dark lanes of dust. The galaxy’s shape may seem a little unusual, and that’s because it’s what’s known as an “intermediate galaxy”: not quite a barred spiral, but not exactly an unbarred spiral, either ― a hybrid of the two.

How NASA will shield its solar probe from crazy heat
A heat shield you can scorch with a blowtorch until it glows red on one side and still comfortably touch on the other will protect a NASA probe flying to within 4 million miles of the sun’s surface. The shield is the culmination of years of work by engineers to solve what they call the “thermal problem” of the soon-to-launch Parker Solar Probe.
Can the Parker Solar Probe take the heat?
By Tracy Vogel / Published Aug 6, 2018 The star of the show is a dark gray block, about the size of a textbook, and several inches thick. As an audience of reporters watches, an engineer runs a flaming blowtorch over the block until its face heats to a red glow. "You want to take a touch of the back surface?" she invites a NASA T-shirt-clad volunteer. The volunteer reaches tentatively out to the back, first with one finger, and then with her whole hand.
