Hubble 28th Anniversary Image Captures Roiling Heart of Vast Stellar Nursery



For 28 years, NASA’s Hubble Space Telescope has been delivering breathtaking views of the universe. Although the telescope has made more than 1.5 million observations of over 40,000 space objects, it is still uncovering stunning celestial gems.

The latest offering is this image of the Lagoon Nebula to celebrate the telescope’s anniversary. Hubble shows this vast stellar nursery in stunning unprecedented detail.

At the center of the photo, a monster young star 200,000 times brighter than our Sun is blasting powerful ultraviolet radiation and hurricane-like stellar winds, carving out a fantasy landscape of ridges, cavities, and mountains of gas and dust. This region epitomizes a typical, raucous stellar nursery full of birth and destruction.

Celebratory Galaxy Photo Honors 25th Anniversary of NASA's First Hubble Servicing Mission



Over the past 28 years Hubble has photographed innumerable galaxies throughout the universe, near and far. But one especially photogenic galaxy located 55 million light-years away holds a special place in Hubble history. As NASA made plans to correct Hubble's blurry vision in 1993 (due to a manufacturing flaw in its primary mirror) they selected several astronomical objects that Hubble should be aimed at to demonstrate the planned optical fix. The magnificent grand spiral galaxy M100 seemed an ideal target that would just fit inside Hubble's field-of-view. This required that a comparison photo be taken while Hubble was still bleary-eyed. The Wide Field/Planetary Camera 1 was selected for the task. And, the picture had to be taken before astronauts swapped-out the camera with the vision-corrected Wide Field/Planetary Camera 2, in December 1993. Following the servicing mission Hubble re-photographed the galaxy again, and it snapped into crystal clear focus. The public celebrated with Hubble's triumphant return to the clear vision that had been promised. And, jaw-dropping pictures of the vast universe that followed have not disappointed space enthusiasts. Because of the astronaut servicing missions, Hubble's capabilities have only gotten better. To commemorate the 25th anniversary of the first servicing mission, this 2-panel photo compares the blurry, pre-servicing 1993 image to a 2009 image taken with Hubble's newer, Wide Field Camera 3 instrument, installed during the last astronaut servicing mission to the space telescope.

Hubble Uncovers Thousands of Globular Star Clusters Scattered Among Galaxies



Globular star clusters are favorite targets for amateur sky watchers. To the naked eye they appear as fuzzy-looking stars. Through a small telescope they resolve into glittering snowball-shaped islands of innumerable stars crowded together. About 150 globular star clusters orbit our Milky Way, like bees buzzing around a hive. They are the earliest homesteaders of our galaxy, containing the universe's oldest known stars.

Hubble is so powerful it can see globular star clusters 300 million light-years away. And, a lot of them. Peering into the heart of the giant Coma cluster of galaxies Hubble captured a whopping 22,426 globular star clusters. The survey found the globular clusters scattered in space among the 1,000 galaxies inside the Coma cluster. They have been orphaned from their home galaxy due to galaxy near-collisions inside the traffic-jammed galaxy cluster. Because they are so numerous in the Coma cluster, they are excellent tracers of the entire gravitational field that keeps the galaxies from flinging off into space. The gravity is a tracer of the distribution of dark matter.

New Virtual Reality Experience Highlights NASA’s Webb Space Telescope



Visit the James Webb Space Telescope at its orbit point beyond the Moon, 1 million miles from Earth. Fly through the Orion Nebula and watch a planet-forming disk take shape. Explore the star fields of a simulated galaxy. Or get hands-on and fling stars into a ravenous black hole to watch them spaghettify. All of these encounters are part of the new WebbVR virtual experience.

WebbVR offers users an opportunity to immerse themselves into a variety of environments from our own solar system to distant galaxies. Information hubs provide more details about the places you visit, while simulations incorporate real physics. WebbVR is available for download from Steam, a popular VR content platform.

NASA's Webb Telescope Will Provide Census of Fledgling Stars in Stellar Nursery



Billions of years ago, the young universe blazed with the brilliant light of myriad stars bursting to life. The young stars arising from this stellar "baby boom" are too far away and too faint for even the most powerful telescopes to study in detail.

Astronomers will use the upcoming NASA James Webb Space Telescope to study star birth in the nearby Small Magellanic Cloud galaxy, which contains some of the same conditions that existed in galaxies during the universe’s peak star-formation epoch. Webb’s sharp infrared vision will help researchers take a census of medium-mass stars like our Sun still wrapped in their dense, dusty cocoons in the giant stellar nursery NGC 346, located about 200,000 light-years away. This census could help astronomers develop a clearer picture of how the galaxies of long ago churned out stars so rapidly.

In Search of Missing Worlds, Hubble Finds a Fast Evaporating Exoplanet



In nabbing exoplanets that are precariously close to their stars, astronomers have discovered a shortage of one type of alien world. It's a predicted class of Neptune-sized world that orbits just a few million miles from its star, much closer than the 93-million-mile distance between Earth and the Sun. Dubbed "hot Neptunes," these planets would have atmospheres that are heated to more than 1,700 degrees Fahrenheit (hot enough to melt silver).

However, the mysterious hot-Neptune deficiency suggests that these planets are rare, or, they were plentiful at one time, but have since disappeared. In fact, most of the known Neptune-sized exoplanets are merely "warm," because they orbit farther away from their star than those in the region where astronomers would expect to find hot Neptunes.

To date, astronomers have discovered two warm Neptunes that are leaking their atmospheres into space. The most recent finding, a planet cataloged as GJ 3470b, is losing its atmosphere at a rate 100 times faster than that of the previously discovered evaporating warm Neptune, GJ 436b.

These discoveries reinforce the idea that the hotter version of these distant worlds may be a class of transitory planet whose ultimate fate is to shrink down to the most common type of known exoplanet, mini-Neptunes — planets with heavy, hydrogen-dominated atmospheres that are larger than Earth but smaller than Neptune. Eventually, these planets may downsize even further to become super-Earths, more massive, rocky versions of Earth. If GJ 3470b continues to rapidly lose mass, in a few billion years, perhaps it, too, will dwindle to a mini-Neptune.

Behind the Scenes of Recovering NASA's Hubble



In the early morning of October 27, 2018, the Hubble Space Telescope targeted a field of galaxies not far from the Great Square in the constellation Pegasus. Contained in the field were star-forming galaxies up to 11 billion light-years away. With the target in its sights, Hubble's Wide Field Camera 3 recorded an image. It was the first picture captured by the telescope since it closed its eyes on the universe three weeks earlier, and it was the result of an entire team of engineers and experts working tirelessly to get the telescope exploring the cosmos once again.
