European Southern Observatory Telescopes Help Solve Pulsar Puzzle

European Southern Observatory Telescopes Help Solve Pulsar Puzzle


ESOcast 266 Light: With a remarkable observational campaign that involved 12 telescopes both on the ground and in space, including three European Southern Observatory (ESO) facilities, astronomers have uncovered the strange behavior of a pulsar, a super-fast-spinning dead star. This video summarizes the discovery.

A pulsar is a fast-rotating, magnetic, dead star that emits a beam of electromagnetic radiation into space. As it rotates, this beam sweeps across the cosmos—much like a lighthouse beam scanning its surroundings—and is detected by astronomers as it intersects the line of sight to Earth. This makes the star appear to pulse in brightness as seen from our planet.

PSR J1023+0038, or J1023 for short, is a special type of pulsar with a bizarre behavior. Located about 4,500 light-years away in the Sextans constellation, it closely orbits another star. Over the past decade, the pulsar has been actively pulling matter off this companion, which accumulates in a disc around the pulsar and slowly falls towards it. 

Since this process of accumulating matter began, the sweeping beam virtually vanished and the pulsar started incessantly switching between two modes. In the ‘high’ mode, the pulsar gives off bright X-rays, ultraviolet and visible light, while in the ‘low’ mode it is dimmer at these frequencies and emits more radio waves. The pulsar can stay in each mode for several seconds or minutes, and then switch to the other mode in just a few seconds. This switching has thus far puzzled astronomers.  

In the low mode, matter flowing towards the pulsar is expelled in a narrow jet perpendicular to the disc. Gradually, this matter accumulates closer and closer to the pulsar and, as this happens, it is hit by the wind blowing from the pulsating star, causing the matter to heat up. The system is now in a high mode, glowing brightly in the X-ray, ultraviolet and visible light. Eventually, blobs of this hot matter are removed by the pulsar via the jet. With less hot matter in the disc, the system glows less brightly, switching back into the low mode.

NASA Psyche Mission Power Electronics Engineer Meena Sreekantamurthy | JPL

NASA Psyche Mission Power Electronics Engineer Meena Sreekantamurthy | JPL

Behind the Spacecraft: Meet Meena Sreekantamurthy, a power electronics engineer on NASA’s Psyche mission, which will be the first to explore a metal-rich asteroid, also named Psyche. In this video, Sreekantamurthy, from the Johns Hopkins University Applied Physics Laboratory, explains how power is critical for gathering the mission’s science data. She also talks about her passion for painting and drawing.

Whether the asteroid Psyche is the partial core of a planetesimal (a building block of the rocky planets in our solar system) or primordial material that never melted, scientists expect the mission to help answer fundamental questions about Earth’s own metal core and the formation of our solar system. 

This is the second episode in a weekly, five-part video series called “Behind the Spacecraft.” Each Psyche team member will tell the story of how they came to the mission.

Psyche’s launch period opens Oct. 5, 2023. The spacecraft will begin orbiting the asteroid Psyche in 2029.

SpaceX Crew-8 Mission Insignia

NASA's SpaceX Crew-8 poses for group photos after completing the first full week of training at SpaceX in Hawthorne, California. SpaceX Crew 8 members are Mission Specialist Aleksandr Grebenkin from Roscosmos (Russia), Pilot Michael Barratt, Commander Matthew Dominick, and Mission Specialist Jeanette Epps—the last three all from NASA. They will join Expedition 70 and 71 crew members aboard the International Space Station in early 2024 to conduct a wide-ranging set of operational and research activities.

This will be Epps’ first trip to the International Space Station. She is from Syracuse, New York, and earned a bachelor’s in physics from LeMoyne College in Syracuse, New York, and a master’s in science and a doctorate in aerospace engineering from the University of Maryland, College Park. Prior to joining NASA, she worked at Ford Motor Company and the Central Intelligence Agency. She was selected as an astronaut in July 2009, and has served on the Generic Joint Operation Panel working on space station crew efficiency, as a crew support astronaut for two expeditions, and as lead capsule communicator in the Mission Control Center at NASA’s Johnson Space Center in Houston. Epps previously was assigned to NASA’s Boeing Starliner-1 mission. NASA reassigned Epps to allow Boeing time to complete development of Starliner while also continuing plans for astronauts to gain spaceflight experience for future mission needs.

This will also be the first spaceflight for Dominick, who became a NASA astronaut in 2017. He is from Wheat Ridge, Colorado, and earned a bachelor’s degree in electrical engineering from the University of San Diego, California, and a master’s in systems engineering from the Naval Postgraduate School in Monterey, California. He is an active-duty U.S. Navy astronaut. He graduated from the U.S. Naval Test Pilot School in Patuxent River, Maryland, and then served as a test pilot specializing in testing landing on and catapult launches from U.S. Navy aircraft carriers.

This will be Barratt’s third trip to the space station. In 2009, Barratt served as a flight engineer for Expeditions 19 and 20 as the station transitioned its standard crew complement from three to six, and performed two spacewalks. He flew aboard the space shuttle Discovery in 2011 on STS-133, which delivered the Permanent Multipurpose Module and fourth Express Logistics Carrier. He has spent a total of 212 days in space. Born in Vancouver, Washington, he considers Camas, Washington, to be his hometown. Barratt earned a bachelor’s in zoology from the University of Washington, Seattle, and a doctor of medicine from Northwestern University in Chicago, Illinois. He completed residencies in internal medicine at Northwestern and aerospace medicine along with a master’s degree at Wright State University in Dayton, Ohio. After nine years as a NASA flight surgeon and project physician, Barratt joined the astronaut corps in 2000.


Grebenkin, who graduated from Irkutsk High Military Aviation School, Irkutsk, Russia, majoring in engineering, maintenance, and repair of aircraft radio navigation systems, is flying on his first mission, too. He graduated from Moscow Technical University of Communications and Informatics with a degree in radio communications, broadcasting, and television.

This is the eighth rotational mission to the space station under NASA’s Commercial Crew Program, which works with the American aerospace industry to provide safe, reliable, and cost-effective transportation to and from the orbital outpost on American-made rockets and spacecraft launching from American soil.

For more than 22 years, humans have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies, making research breakthroughs not possible on Earth. As a global endeavor, 244 people from 19 countries have visited the unique microgravity laboratory that has hosted more than 3,000 research and educational investigations from researchers in 108 countries and areas.

The station is a critical testbed for NASA to understand and overcome the challenges of long-duration spaceflight and to expand commercial opportunities in low Earth orbit. As commercial companies focus on providing human space transportation services and destinations as part of a robust low Earth orbit economy, NASA is able to more fully focus its resources on deep space missions to the Moon and Mars.

The Australian Outback & NASA's Search for Life on Mars | NASA Astrobiology

The Australian Outback & NASA's Search for Life on Mars | NASA Astrobiology

How will we know if there is life on Mars? What geological clues can our Martian orbiters and rovers search for and collect samples of to return home to Earth?

Stromatolites in the Pilbara region of Western Australia may hold the answer.

In June 2023, members of NASA's Mars Exploration Program, the Australian Space Agency, the European Space Agency, and the Australian Commonwealth Scientific and Industrial Research Organization (CSIRO), joined together on an expedition to visit three incredible field locations containing stromatolites, fossils of ancient microbial life, and the oldest, most convincing evidence for life on Earth.

Stromatolites are rock features that are usually dome or cone-shaped, and are caused by photosynthetic lifeforms precipitating minerals throughout their life cycle, while continuously climbing upwards towards their energy source of the sun. Over time these microbial communities begin to form layers of rock that rise up to form strange shapes in the geological record that cannot be formed in any other way. Could these structures be found on other planets? On Mars?

As we search the solar system and beyond for biosignatures, or signs of life, it is crucial that we know as much as possible about the nature of life on Earth. Knowing how quickly life took hold on our planet, and how that life evolved over time, will help NASA scientists understand the possibilities for life on other worlds and how best to search for them. Mars and Earth may have had very similar pasts, and the surface of Mars shares many qualities with the stromatolite outcrops in Western Australia.

If life could take a foothold on Earth 3.5 billion years ago, could it also have taken a hold on Mars?

NASA acknowledges the Traditional Custodians of country throughout Australia and their connections to land, sea, and community. We pay out respect to their Elders past and present and extend that respect to all Aboriginal and Torres Strait Islander peoples today.

The Whirlpool Galaxy: M51 | James Webb Space Telescope

The Whirlpool Galaxy: M51 | James Webb Space Telescope

The graceful winding arms of the grand-design spiral galaxy M51 stretch across this image from the NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope. M51—also known as NGC 5194—lies about 27 million light-years away from Earth in the constellation Canes Venatici, and is trapped in a tumultuous relationship with its near neighbor, the dwarf galaxy NGC 5195. The interaction between these two galaxies has made these galactic neighbors one of the better-studied galaxy pairs in the night sky. The gravitational influence of M51’s smaller companion is thought to be partially responsible for the stately nature of the galaxy’s prominent and distinct spiral arms.  It was the first galaxy to be classified as a spiral galaxy.

Unlike the menagerie of weird and wonderful spiral galaxies with ragged or disrupted spiral arms, grand-design spiral galaxies boast prominent, well-developed spiral arms like the ones showcased in this image. This galactic portrait is a composite image that integrates data from Webb’s Near-InfraRed Camera (NIRCam) and Mid-InfraRed Instrument (MIRI).

In this image the dark red regions trace the filamentary warm dust permeating the medium of the galaxy. The red regions show the reprocessed light from complex molecules forming on dust grains, while colors of orange and yellow reveal the regions of ionized gas by the recently formed star clusters. Stellar feedback has a dramatic effect on the medium of the galaxy and create complex network of bright knots as well as cavernous black bubbles.

Image Description: A large spiral galaxy takes up the entirety of the image. The core is mostly bright white, but there are also swirling, detailed structures that resemble water circling a drain. There is white and pale blue light that emanates from stars and dust at the core’s center, but it is tightly limited to the core. The rings feature colors of deep red and orange and highlight filaments of dust around cavernous black bubbles.

This Webb observation of M51 is one of a series of observations collectively titled Feedback in Emerging extrAgalactic Star clusTers, or FEAST. The FEAST observations were designed to shed light on the interplay between stellar feedback and star formation in environments outside of our own galaxy, the Milky Way. Stellar feedback is the term used to describe the outpouring of energy from stars into the environments which form them, and is a crucial process in determining the rates at which stars form. Understanding stellar feedback is vital to building accurate universal models of star formation.

The aim of the FEAST observations is to discover and study stellar nurseries in galaxies beyond our own Milky Way. Before Webb became operative, other observatories, such as the Atacama Large Millimetre Array in the Chilean desert and Hubble, have given us a glimpse of star formation either at the onset (tracing the dense gas and dust clouds where stars will form) or after the stars have destroyed with their energy their natal gas and dust clouds. Webb is opening a new window into the early stages of star formation and stellar light, as well as the energy reprocessing of gas and dust. Scientists are seeing star clusters emerging from their natal cloud in galaxies beyond our local group for the first time. They will also be able to measure how long it takes for these stars to pollute with newly formed metals and to clean out the gas (these time scales are different from galaxy to galaxy). By studying these processes, we will better understand how the star formation cycle and metal enrichment are regulated within galaxies as well as what are the time scales for planets and brown dwarfs to form. Once dust and gas is removed from the newly formed stars, there is no material left to form planets.

Reflection Nebula NGC 1333: Infrared view | NASA's Spitzer Space Telescope

Reflection Nebula NGC 1333: Infrared view | NASA's Spitzer Space Telescope

Located 1,000 light-years from Earth in the constellation Perseus, a reflection nebula called NGC 1333 epitomizes the beautiful chaos of a dense group of stars being born. Most of the visible light from the young stars in this region is obscured by the dense, dusty cloud in which they formed. With NASA's Spitzer Space Telescope, scientists can detect the infrared light from these objects. This allows a look through the dust to gain a more detailed understanding of how stars like our sun begin their lives.

The young stars in NGC 1333 do not form a single cluster, but are split between two sub-groups. One group is to the north near the nebula shown as red in the image. The other group is south, where the features shown in yellow and green abound in the densest part of the natal gas cloud. With the sharp infrared eyes of Spitzer, scientists can detect and characterize the warm and dusty disks of material that surround forming stars. By looking for differences in the disk properties between the two subgroups, they hope to find hints of the star- and planet-formation history of this region.

The knotty yellow-green features located in the lower portion of the image are glowing shock fronts where jets of material, spewed from extremely young embryonic stars, are plowing into the cold, dense gas nearby. The sheer number of separate jets that appear in this region is unprecedented. This leads scientists to believe that by stirring up the cold gas, the jets may contribute to the eventual dispersal of the gas cloud, preventing more stars from forming in NGC 1333.

In contrast, the upper portion of the image is dominated by the infrared light from warm dust, shown as red.

The SLS RS-25 Moon Rocket Engine: Eight Minutes of Pure Power | NASA Marshall

The SLS RS-25 Moon Rocket Engine: Eight Minutes of Pure Power | NASA Marshall

When NASA’s Space Launch System (SLS) rocket roars to life on the launch pad, NASA’s Artemis astronauts inside the Orion spacecraft will feel the power of the rocket’s four RS-25 engines for eight minutes. The four RS-25 engines on SLS are the most efficient engines ever built. Two giant propellant tanks on the SLS core stage provide the fuel to power the engines that, together, provide more than 2 million pounds of thrust to help launch NASA’s Artemis missions to the Moon. 

The RS-25 engines are produced by Aerojet Rocketdyne, an L3Harris Technologies Company. Watch this video to learn more about how these engines have been adapted from the Space Shuttle Program for the SLS rocket’s bold missions into deep space.

Watch the "Ring of Fire" Solar Eclipse: Coming Oct. 14, 2023 | NASA

Watch the "Ring of Fire" Solar Eclipse: Coming Oct. 14, 2023 | NASA

On Oct. 14, 2023, a “ring of fire,” or annular, solar eclipse will travel from Oregon coast to the Gulf of Mexico. Weather permitting, most of the Americas will be able to view at least a partial solar eclipse. Click here to see the NASA 2023 and 2024 Solar Eclipse Map: https://go.nasa.gov/USEclipseMaps 

An annular solar eclipse occurs when the Moon passes between the Sun and the Earth, but is just far away enough in its orbit that the Sun is not completely covered—creating a large, bright ring in the sky.

WARNING: During an annular eclipse, it is never safe to look directly at the Sun without specialized eye protection designed for solar viewing. How to safely view an eclipse:

Not in the path of the eclipse? Watch with us from anywhere in the world. We will provide live broadcast coverage on Oct. 14 from 11:30 a.m. to 1:15 p.m. EDT (1530-1715 UTC) on NASA TV, NASA.gov and the NASA app.

Reflection Nebula NGC 1333 in Perseus: Wide-field view | Mayall Telescope

Reflection Nebula NGC 1333 in Perseus: Wide-field view | Mayall Telescope


This image of reflection nebula NGC 1333 was taken using the Mosaic-1 imager and the National Science Foundation’s 4-meter Mayall Telescope at Kitt Peak National Observatory (KPNO). This star-forming region, located roughly 1,000 light-years from Earth in the direction of the constellation Perseus, harbors hundreds of newly formed stars less than one million years old. Many of these proto-stars exhibit energetic activity, such as jets and strong stellar winds.
