In January 2002, a dull star in an obscure constellation suddenly became 600,000 times more luminous than our Sun, temporarily making it the brightest star in our Milky Way galaxy. The mysterious star, called V838 Monocerotis, has long since faded back to obscurity. But observations by NASA's Hubble Space Telescope of a phenomenon called a "light echo" around the star have uncovered remarkable new features. These details promise to provide astronomers with a CAT-scan-like probe of the three-dimensional structure of shells of dust surrounding an aging star.

      (Oct. 25, 2024) — NASA astronaut and Expedition 72 Commander Suni Williams is pictured at the galley inside the International Space Station’s Unity module at the beginning of her day.Credit: NASA Students from Colorado will have the opportunity to hear NASA astronauts Nick Hague and Suni Williams answer their prerecorded questions aboard the International Space Station on Thursday, Nov. 14.
      Watch the 20-minute space-to-Earth call at 1 p.m. EST on NASA+. Learn how to watch NASA content on various platforms, including social media.
      The JEKL Institute for Global Equity and Access, in partnership with the Denver Museum of Nature and Science, will host students from the Denver School of Science and Technology for the event. Students are building CubeSat emulators to launch on high-altitude balloons, and their work will drive their questions with crew.
      Media interested in covering the event must RSVP by 5 p.m., Wednesday, Nov. 13, to Daniela Di Napoli at: daniela.dinapoli@scienceandtech.org or 832-656-5231.
      For more than 24 years, astronauts have continuously lived and worked aboard the space station, testing technologies, performing science, and developing skills needed to explore farther from Earth. Astronauts aboard the orbiting laboratory communicate with NASA’s Mission Control Center in Houston 24 hours a day through SCaN’s (Space Communications and Navigation) Near Space Network.
      Important research and technology investigations taking place aboard the space station benefit people on Earth and lays the groundwork for other agency missions. As part of NASA’s Artemis campaign, the agency will send astronauts to the Moon to prepare for future human exploration of Mars; inspiring Artemis Generation explorers and ensuring the United States continues to lead in space exploration and discovery.

      NASA/Loral O’Hara The Choctaw Heirloom Seeds investigation flew five varieties of heirloom seeds from the Choctaw Nation of Oklahoma aboard the International Space Station in early November 2023. The seeds are Isito (Choctaw Sweet Potato Squash), Tobi (Smith Peas), Tanchi Tohbi (Flour Corn), Tvnishi (Lambsquarter), and Chukfi Peas. The seeds spent six months aboard station, returning to Earth in April 2024.
      Next spring, Jones Academy students will plant the space-flown seeds alongside Earth-bound seeds of the same type in the school’s Growing Hope Garden. Students will hypothesize how the seeds will grow and make observations throughout the growing season.
      Middle school teachers are developing curriculum incorporating the seeds’ journey to space station and students’ experiments in the garden. This research could impact Native and Indigenous populations across the United States, inviting underrepresented groups to engage with science, technology, engineering, and mathematics.

      Director Vanessa Wyche of NASA’s Johnson Space Center in Houston will join Texas A&M University leaders and guests Friday, Nov. 15, to break ground for the new Texas A&M University Space Institute.
      U.S. media interested in participating in person must contact the NASA Johnson newsroom no later than 5 p.m. Wednesday, Nov. 13, by calling 281-483-5111 or emailing: jsccommu@mail.nasa.gov. NASA’s media accreditation policy is available online.
      The groundbreaking is planned for 10 a.m. CST Nov. 15, at Johnson Space Center’s Exploration Park. Additional participants will include:
      Greg Bonnen, Texas House of Representatives, chairman of House Appropriations Committee William Mahomes, Jr., Board of Regents chairman, Texas A&M University System  John Sharp, chancellor Texas A&M University System  General (Ret.) Mark Welsh III, president, Texas A&M University  Robert H. Bishop, vice chancellor and dean, Texas A&M Engineering Nancy Currie-Gregg, director, Texas A&M University Space Institute Robert Ambrose, associate director for space and robotics initiatives, Texas A&M Engineering Experiment Station  The institute, funded through a $200 million initial investment from the State of Texas, will support research for civilian, defense and commercial space missions as part of NASA Johnson’s Exploration Park. Key features will include the world’s largest indoor simulation spaces for lunar and Mars surface operations, state-of-the-art high-bay laboratories, and multifunctional project rooms.
      The Texas A&M Space Institute is set to open in Summer 2026. 
      NASA is leasing the 240-acre Exploration Park to create facilities that enable a collaborative development environment, increase commercial access, and enhance the United States’ commercial competitiveness in the space and aerospace industries.

Zamani (ESA/Hubble) This NASA/ESA Hubble Space Telescope image features NGC 1672, a barred spiral galaxy located 49 million light-years from Earth in the constellation Dorado. This galaxy is a multi-talented light show, showing off an impressive array of different celestial lights. Like any spiral galaxy, shining stars fill its disk, giving the galaxy a beautiful glow. Along its two large arms, bubbles of hydrogen gas shine in a striking red light fueled by radiation from infant stars shrouded within. Near the galaxy’s center are some particularly spectacular stars embedded within a ring of hot gas. These newly formed and extremely hot stars emit powerful X-rays. Closer in, at the galaxy’s very center, sits an even brighter source of X-rays, an active galactic nucleus. This X-ray powerhouse makes NGC 1672 a Seyfert galaxy. It forms as a result of heated matter swirling in the accretion disk around NGC 1672’s supermassive black hole.

      This NASA/ESA Hubble Space Telescope image features NGC 1672, a barred spiral galaxy located 49 million light-years from Earth in the constellation Dorado. This galaxy is a multi-talented light show, showing off an impressive array of different celestial lights. Like any spiral galaxy, shining stars fill its disk, giving the galaxy a beautiful glow. Along its two large arms, bubbles of hydrogen gas shine in a striking red light fueled by radiation from infant stars shrouded within. Near the galaxy’s center are some particularly spectacular stars embedded within a ring of hot gas. These newly formed and extremely hot stars emit powerful X-rays. Closer in, at the galaxy’s very center, sits an even brighter source of X-rays, an active galactic nucleus. This X-ray powerhouse makes NGC 1672 a Seyfert galaxy. It forms as a result of heated matter swirling in the accretion disk around NGC 1672’s supermassive black hole.
      Image Before/After Along with its bright young stars and X-ray core, a highlight of this image is the most fleeting and temporary of lights: a supernova, visible in just one of the six Hubble images that make up this composite. Supernova SN 2017GAX was a Type I supernova caused by the core-collapse and subsequent explosion of a giant star that went from invisible to a new light in the sky in just a matter of days. In the image above, the supernova is already fading and is visible as a small green dot just below the crook of the spiral arm on the right side. Astronomers wanted to look for any companion star that the supernova progenitor may have had — something impossible to spot beside a live supernova — so they purposefully captured this image of the fading supernova.
      Recently, NGC 1672 was also among a crop of galaxies imaged with the NASA/ESA/CSA James Webb Space Telescope, showing the ring of gas and the structure of dust in its spiral arms. The image below compares the Webb image with Hubble’s image.
