Evidence for Neutron Star Inside SN 1987a Supernova Remnant | NASA Webb

Evidence for Neutron Star Inside SN 1987a Supernova Remnant | NASA Webb

The NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope has found the best evidence yet for emission from a neutron star at the site of a recently observed supernova. The supernova, known as SN 1987A, occurred 160,000 light-years from Earth in the neighboring Large Magellanic Cloud galaxy. SN 1987A was a type II supernova that was observed on Earth in 1987, the first supernova that was visible to the naked eye since 1604—before the advent of telescopes. It provided the astronomical community a rare opportunity to study the evolution of a supernova and what was left behind, from the very beginning. SN 1987A was a core-collapse supernova, meaning the compacted remains at its core are expected to have formed either a neutron star or a black hole. Evidence for such a compact object has long been sought, and whilst indirect evidence for the presence of a neutron star has previously been found, this is the first time that the effects of high energy emission from the young neutron star has been detected.

LEFT: Webb’s 2023 NIRCam (Near-Infrared Camera) image of SN 1987A that highlights the object’s central structure, expanding with several thousands km/s. The blue region is the densest part of the clumpy ejecta, containing heavy elements like carbon, oxygen, magnesium and iron, as well as dust. The bright ‘ring of pearls’ is the result of the collision of the ejecta with a ring of gas ejected about 20,000 years before the explosion. Now spots are found even exterior to the ring, with diffuse emission surrounding it. These are the locations of supernova shocks hitting more exterior material from the progenitor star. The outer ejecta is now illuminated by X-rays from the collision, while the inner ejecta is powered mainly by radioactivity and a putative compact object.

RIGHT: An international team of astronomers has now used two of Webb’s instruments to study the emissions from the core of SN 1987A. The top image features the data from Webb’s MRS (Medium Resolution Spectrograph) mode of the MIRI instrument (Mid-InfraRed Instrument). The bottom image depicts data from Webb’s NIRSpec (Near Infrared Spectrograph) at shorter wavelengths. Spectral analysis of the MIRI results showed a strong signal due to ionized argon from the center of the ejected material that surrounds the original site of SN 1987A. The NIRSpec data found even more heavily ionized chemical species, particularly five times ionized argon (meaning argon atoms that have lost five of their 18 electrons). Weak lines of ionized sulphur were also detected with MIRI. This indicated to the science team that there is a source of high-energy radiation in the center of the SN 1987A remnant, illuminating an almost point-like region in the center. The most likely source is believed to be a newly born neutron star.

Image Description: A graphic with three images, each of a glowing, ring-shaped nebula. The left side shows a large, full-color image of the nebula and its surroundings, labelled “NIRCam”. A rectangle in the center of the nebula is highlighted and two images of this area are pulled out to the right. Both are shown in shades of orange. The top one is labelled “MIRI MRS Argon II” and the bottom one “NIRSpec IFU Argon VI.

Planet Mars: View of Wilkerson Butte | NASA Mars Curiosity Rover | JPL

Planet Mars: View of Wilkerson Butte | NASA Mars Curiosity Rover | JPL


MSL - sol 4096

This butte on Mars, called "Wilkerson," is located across the Gediz Valley Ridge. It was captured by NASA's Mars Curiosity Rover on sol 4096. In geomorphology, a butte is an isolated hill with steep, often vertical sides and a small, relatively flat top; buttes are smaller landforms than mesas, plateaus, and tablelands. The word butte comes from the French word butte, meaning knoll (but of any size); its use is prevalent in the Western United States, including the southwest where mesa (Spanish for "table") is used for the larger landform. Due to their distinctive shapes, buttes are frequently landmarks in plains and mountainous areas. To differentiate the two landforms, geographers use the rule of thumb that a mesa has a top that is wider than its height, while a butte has a top that is narrower than its height.

Blue Origin's New Glenn Rocket: Preparing for NASA Artemis Moon Missions

Blue Origin's New Glenn Rocket: Preparing for NASA Artemis Moon Missions



Blue Origin's New Glenn vehicle successfully rolled out and upended today for the first time on the pad at Launch Complex 36 (LC-36) in Cape Canaveral, Florida. This milestone represents the first view of the advanced heavy-lift vehicle. It will support a multitude of customer missions and Blue Origin programs, including returning to the Moon as part of NASA’s Artemis program. 

Everything on the pad is New Glenn hardware. The upending is one in a series of major manufacturing and integrated test milestones in preparation for New Glenn’s first launch later this year. The test campaign enables Blue Origin teams to practice, validate, and increase proficiency in vehicle integration, transport, ground support, and launch operations. These tests do not require engines that are now hotfiring at the historic 4670 Test Stand in Huntsville, Alabama, and at Launch Site One in West Texas.

The journey to the pad began in December 2023 when New Glenn’s first-stage modules were transported from Blue Origin's factory to the Integration Facility nine miles away. The tests will conclude in the coming weeks following several demonstrations of cryogenic fluid loading, pressure control, and the vehicle’s venting systems. Blue Origin's launch pad and ground systems are complete and will be activated for the first time during the test campaign. 

New Glenn is named after John Glenn, the first American to orbit Earth. The rocket stands more than 320 feet (98 meters) high—roughly the height of a 30-story building—and features a seven-meter payload fairing, enabling twice the volume of standard five-meter class commercial launch systems. The fairing is large enough to hold three school buses. Its reusable first stage aims for a minimum of 25 missions and will land on a sea-based platform located roughly 620 miles (1,000 km) downrange. Reusability is integral to radically reducing cost-per-launch. 

The vehicle is powered by seven of Blue Origin’s BE-4 engines, the most powerful liquid oxygen (LOX)/liquefied natural gas (LNG) engine developed since Saturn V’s F1 engines. LNG is cleaner-burning and higher-performing than kerosene-based fuels. 

Blue Origin has several New Glenn vehicles in production and a full customer manifest. Customers include NASA, Project Kuiper, Telesat, and Eutelsat, among others.

How Fieldwork in the Amazon is Supporting NASA Climate Science | JPL

How Fieldwork in the Amazon is Supporting NASA Climate Science | JPL

A joint U.S.-India satellite mission called NISAR—the NASA-ISRO Synthetic Aperture Radar (NISAR) mission—will soon set out with new tools to better understand climate change. As a way to validate the satellite’s global, space-based observations, NASA scientists went to the Peruvian Amazon to install a network of sensors that will help calibrate measurements from the NISAR spacecraft.

Why the Amazon? In tropical wetlands, changes in seasonal flooding cycles can lead to increased production of greenhouse gases like methane and carbon dioxide. 

The Amazon rainforest, also called Amazon jungle or Amazonia, is a moist broadleaf tropical rainforest in the Amazon biome that covers most of the Amazon basin of South America. This region includes territory belonging to nine nations and formally acknowledged indigenous territories.

A collaboration between NASA and ISRO (Indian Space Research Organisation), NISAR will use a sophisticated radar system to track wetland inundation and other changes to Earth’s surface. The satellite is expected to launch in early 2024 from ISRO’s Satish Dhawan Space Centre in Sriharikota, India.

IM-1 Robotic Moon Landing Mission Flight Plan (Animation) | Intuitive Machines

IM-1 Robotic Moon Landing Mission Flight Plan (Animation) | Intuitive Machines

Intuitive Machines Chief Technology Officer, Tim Crain Ph.D., covers the overall flightpath of the IM-1 Mission. The IM-1 Mission Nova-C Moon Lander, named "Odysseus", is targeted to touch down at the lunar South Pole at 5:30pm ET (2230 UTC) Feb. 22, 2024. The lander continues to be in excellent health.
All powered NASA science instruments on board have completed their transit checkouts, received data, and are operating as expected, including: LN-1 (Lunar Node 1 Navigation Demonstrator), NDL (Navigation Doppler Lidar for Precise Velocity and Range Sensing), RFMG (Radio Frequency Mass Gauge), ROLSES (Radio-wave Observations at the Lunar Surface of the Photoelectron Sheath), SCALPSS (Stereo Cameras for Lunar Plume-Surface Studies). Since the LRA (Laser Retroreflector Array) instrument is a passive experiment designed for the lunar surface, it cannot conduct any operations in transit.

https://www.intuitivemachines.com/im-1

If all goes well, IM-1 will become the first American spacecraft to set down softly on the Moon’s surface since the NASA Apollo 17 moon landing in 1972.

China's Chang'e 3 Mission, the first Chinese landing on the Moon in 2013, was the first spacecraft to soft-land on the Moon since the Soviet Union's Luna 24 in 1976.

In 2023, after the Chandrayaan-3 Lander successfully soft-landed on the Moon, India became the fourth country, after the United States, Russia and China, to accomplish this.

NASA’s Commercial Lunar Payload Services (CLPS) initiative allows NASA to send science investigations and technology demonstrations to the lunar surface. Under Artemis, NASA will study more of the Moon than ever before, and CLPS will demonstrate how NASA is working with commercial companies to achieve robotic lunar exploration.

What Does a Warming Arctic Mean for the Future? | European Space Agency

What Does a Warming Arctic Mean for the Future? European Space Agency

The Arctic is experiencing disproportionately higher temperature increases compared to the rest of the planet, triggering a series of cascading effects. This rapid warming has profound implications for global climate patterns, human populations and wildlife. 

The Copernicus Imaging Microwave Radiometer mission (CIMR) will provide measurements to decision makers with evidence of change and impact in the polar regions—with a focus on the Arctic. 

The mission has the largest radiometer developed by the European Space Agency (ESA) and will provide high-resolution measurements related to sea ice, the ocean, snow and ice-sheet surfaces. This will be crucial in understanding the evolution of the climate in the polar region.

CIMR is one of six Copernicus Sentinel Expansion missions that ESA is developing on behalf of the EU. The missions will expand the current capabilities of the Copernicus Space Component—"the world’s biggest supplier of Earth observation data."

This video features interviews with Craig Donlon, CIMR Mission Scientist, Rolv Midthassel, CIMR Payload Manager, Claudio Galeazzi, CIMR Project Manager, Mariel Triggianese, CIMR Satellite Engineering and AIV Manager, and Marcello Sallusti, CIMR System Performance and Operations Manager.

In the meantime, Craig has changed his role but will retain his position as Mission Scientist.

Star Clusters: Stellar Beads on a String | NASA's Chandra X-ray Observatory

Star Clusters: Stellar Beads on a String | NASA's Chandra X-ray Observatory

Astronomers have discovered one of the most powerful eruptions from a black hole ever recorded. This mega-explosion billions of years ago may help explain the formation of a striking pattern of star clusters around two massive galaxies, resembling ‘beads on a string.’

This discovery was made in the system known as SDSS J1531, which is located 3.8 billion light-years from Earth. Researchers used several telescopes for this study, including NASA’s Chandra X-ray Observatory, and the Low Frequency Array, or LOFAR, which is a network of radio telescopes in Europe.

SDSS J1531 is a massive galaxy cluster containing hundreds of individual galaxies and huge reservoirs of hot gas and dark matter. In the heart of SDSS J1531, two of the cluster’s largest galaxies are colliding with each other. Surrounding these merging giants is a set of 19 large clusters of stars, called superclusters, arranged in an ‘S’ formation that resembles beads on a string.

A team of astronomers used X-ray, radio and optical data to unravel how this unusual chain of star clusters probably formed. The discovery of evidence for an ancient, titanic eruption in SDSS 1531 provided a vital clue. The eruption likely occurred when the supermassive black hole in the center of one of the large galaxies produced an extremely powerful jet. As the jet moved through space, it pushed the surrounding hot gas away from the black hole, creating a gigantic cavity.

The Chandra data revealed wing-like shaped X-ray emission tracing dense gas near the center of SDSS J1531. These wings are the edge of the cavity and the less dense gas in between is part of the cavity. LOFAR shows radio waves from the remains of the jet’s energetic particles filling in the giant cavity. Together, these data provide compelling signs of an ancient, massive explosion.

How did this giant eruption lead to the unusual pattern of 19 star clusters? The astronomers also found cold and warm gas located near the opening of the cavity using the Atacama Large Millimeter and submillimeter Array, ALMA, and the Gemini North Telescope in Hawaii. They argue that some of the hot gas pushed away from the black hole eventually cooled to form the cold and warm gas seen in the data.

The team thinks tidal effects from the two merging galaxies compressed this gas along curved paths, leading to the star clusters forming in the “beads on a string” pattern. Scientists have witnessed black holes doing many things over the years, but making a string of star clusters may be a first.

A new National Geographic documentary explores the little-known stories of the first Black pilots and engineers who were pioneers of NASA's space program. Geoff Bennett has this look at the film, “The Space Race,” that is streaming on Disney+ and Hulu in the United States. Why did the Soviet Union send a Black person to space first, before America, in 1980 with Arnaldo Tamayo Méndez—a Cuban pilot?
