Hubble’s Inside The Image: Eta Carinae—Great Eruption of a Massive Star

Hubble’s Inside The Image: Eta Carinae—Great Eruption of a Massive Star

The Hubble Space Telescope has taken over 1.5 million observations over the years. One of them is the breathtaking image of Eta Carinae. Eta Carinae was the site of a giant outburst about 150 years ago, when it became one of the brightest stars in the southern sky. Though the star released as much visible light as a supernova explosion, it survived the outburst. Somehow, the explosion produced two polar lobes and a large thin equatorial disk, all moving outward at about 1.5 million miles per hour.

In this video, Dr. Keith Noll explains this breathtaking image and explains how important Hubble is to exploring the mysteries of the universe.

Zooming into Star Cluster NGC 6520 & Dark Cloud Barnard 86 | ESO

This video sequence starts with a view of the spectacular Milky Way. As we zoom in towards the center we see a huge cloud of faint stars, this is the Large Sagittarius Star Cloud. On top of this cloud there is a much smaller dark feature called Barnard 86 and in the final view from the MPG/ESO 2.2-meter telescope at the European Southern Observatory's La Silla Observatory in Chile we see not only the gecko-shaped dark cloud but also its neighboring star cluster NGC 6520.

International Students Visit World's Largest Single-dish Radio Telescope in China

International Students Visit World's Largest Single-dish Radio Telescope in China

"I didn't expect the telescope can be so gigantic." Forty international students recently visited China's five-hundred-meter Aperture Spherical Radio Telescope (FAST), the world's largest single-dish radio telescope, constructed in 2016. Fast radio bursts, or FRBs, are one of the greatest mysteries of our universe. FAST has already reported the largest set of FRB events ever detected in history. For example, between August and October 2019, the Five-Hundred-Meter Aperture Spherical Radio Telescope (FAST) in southwestern China recorded a total of 1,652 such brief and bright outbursts from a single repeating FRB source in a dwarf galaxy three billion light years away.

“The study is very thorough, with a level of details and sensitivity we’ve never had before,” says astrophysicist Emily Petroff from the University of Amsterdam in the Netherlands and McGill University in Canada

Coming from deep space, these fast radio bursts can flash and fade in a matter of milliseconds, yet in each instance can release as much energy as the sun does in a year. They pop up all across the sky multiple times a day, but most appear to be one-off events and are thus hard to catch. First discovered in 2007, FRBs have challenged and tantalized scientists seeking to uncover their obscure origins and to use them as unique tools for probing the depths of intergalactic space.

The primary driving force behind the FAST project was Nan Rendong, a researcher with the Chinese National Astronomical Observatory, part of the Chinese Academy of Sciences. He held the positions of chief scientist and chief engineer of the project. He died September 15, 2017, in Boston due to lung cancer.

NASA Crews Spray Foam Insulation on Artemis III Moon Rocket Hardware

NASA Crews Spray Foam Insulation on Artemis III Moon Rocket Hardware

Teams at NASA’s Marshall Space Flight Center in Huntsville, Alabama, have completed applying a spray-on foam insulation to the launch vehicle stage adapter (LVSA) for the Artemis III mission. The LVSA is a cone-shaped piece of hardware that connects the SLS (Space Launch System) rocket’s upper and lower stages and partially encloses the engine of the interim cryogenic propulsion stage. The spray-on foam insulation is a type of thermal protection system that is used to protect the Moon rocket’s hardware from the extreme temperatures, forces, and sounds it will experience during launch and ascent. Unlike other parts of the mega rocket, the thermal protection system for the LVSA is applied entirely by hand using a tool similar to a spray gun. It is the largest piece of SLS hardware to be hand sprayed. Teams started applying the thermal protection system in March 2023.

The LVSA in this video will be used for Artemis III, the mission that will land the first woman and first person of color on the lunar surface. The LVSA is fully manufactured at Marshall by NASA, lead contractor Teledyne Brown Engineering, and the Jacobs Space Exploration Group’s ESSCA contract.

Planet Jupiter and Ocean Moon Ganymede | NASA Cassini Mission

Planet Jupiter and Ocean Moon Ganymede | NASA Cassini Mission

Jupiter’s moon Ganymede is proving to be a fascinating world. Not only is it the largest moon in our solar system, bigger than the planet Mercury and the dwarf planet Pluto, but NASA’s Hubble Space Telescope has found the best evidence yet for an underground saltwater ocean on Ganymede. The ocean is thought to have more water than all the water on Earth's surface. Ganymede’s ocean is estimated to be 60 miles (100 kilometers) thick—10 times deeper than Earth's ocean—and is thought to be buried under a 95-mile- (150-kilometer-) thick crust of mostly ice. Identifying liquid water is crucial in the search for habitable worlds beyond Earth and in the search for life as we know it.

The Cassini spacecraft ended its mission on Sept. 15, 2017. Cassini's end involved a series of close Saturn passes, approaching within the rings, then an entry into Saturn's atmosphere to destroy the spacecraft. This method was chosen because it is necessary to ensure protection and prevent biological contamination to any of the moons of Saturn thought to offer potential habitability.

NASA's Space to Ground: Looking for Answers | Week of June 9, 2023

NASA's Space to Ground: Looking for Answers | Week of June 9, 2023

NASA's Space to Ground is your weekly update on what's happening aboard the International Space Station. Expedition 69 Flight Engineers Steve Bowen and Woody Hoburg of NASA concluded their spacewalk June 9, 2023, at 3:28 p.m. EDT after 6 hours and 3 minutes.

Bowen and Hoburg completed all of their objectives to install an IROSA (International Space Station Roll-Out Solar Array) to augment power generation for the 1A power channel on the station’s starboard truss structure. The crew members also completed several get ahead tasks setting the stage for the duo to go back outside Thursday, June 15, to install the sixth in the series of IROSAs on the starboard 6 truss of the station for the 1B power channel.

The new arrays are 60 feet long by 20 feet wide (18.2 meters by 6 meters) and will shade a little more than half of the original arrays, which are 112 feet long by 39 feet wide. Each new IROSA will produce more than 20 kilowatts of electricity, and once all are installed, will enable a 30% increase in power production over the station’s current arrays.

It was the 264th spacewalk in support of space station assembly, upgrades, and maintenance, and was the third spacewalk for both astronauts.

Bowen and Hoburg are in the midst of a science mission living and working aboard the microgravity laboratory to advance scientific knowledge and demonstrate new technologies for future human and robotic exploration missions, including lunar missions through NASA’s Artemis program.

Saturn's Moon Titan: Thick Atmosphere with Rivers, Lakes & Seas | NASA Cassini

Saturn's Moon Titan: Thick Atmosphere with Rivers, Lakes & Seas | NASA Cassini

Saturn’s largest moon Titan is an extraordinary and exceptional world. Among our solar system’s more than 150 known moons, Titan is the only one with a substantial atmosphere. And of all the places in the solar system, Titan is the only place besides Earth known to have liquids in the form of rivers, lakes and seas on its surface.

Titan is larger than the planet Mercury and is the second largest moon in our solar system. Jupiter's moon Ganymede is just a little bit larger (by about 2 percent). Titan’s atmosphere is made mostly of nitrogen, like Earth’s, but with a surface pressure 50 percent higher than Earth’s. Titan has clouds, rain, rivers, lakes and seas of liquid hydrocarbons like methane and ethane. The largest seas are hundreds of feet deep and hundreds of miles wide. Beneath Titan’s thick crust of water ice is more liquid—an ocean primarily of water rather than methane. Titan’s subsurface water could be a place to harbor life as we know it, while its surface lakes and seas of liquid hydrocarbons could conceivably harbor life that uses different chemistry than we are used to—that is, life as we do not yet know it.

NASA Extracts Oxygen From Lunar Soil Simulant | Johnson Space Center

NASA Extracts Oxygen from Lunar Soil Simulant | Johnson Space Center

Resources like oxygen are crucial building blocks in NASA’s plans to establish a long-term presence on the lunar surface. In addition to using oxygen for breathing, it can also be used as a propellant for transportation, helping lunar visitors stay longer and venture farther.

During a recent test, scientists at NASA’s Johnson Space Center in Houston successfully extracted oxygen from simulated lunar soil. Lunar soil refers to the fine-grained material covering the Moon’s surface.

This was the first time that this extraction has been done in a vacuum environment, paving the way for astronauts to one day extract and use resources to “live off the land” in a lunar environment.
