Frosty white water ice clouds and swirling orange dust storms above a vivid rusty landscape reveal Mars as a dynamic planet in this sharpest view ever obtained by an Earth-based telescope. The Earth-orbiting Hubble telescope snapped this picture on June 26, when Mars was approximately 43 million miles (68 million km) from Earth -- its closest approach to our planet since 1988. Hubble can see details as small as 10 miles (16 km) across. Especially striking is the large amount of seasonal dust storm activity seen in this image. One large storm system is churning high above the northern polar cap [top of image], and a smaller dust storm cloud can be seen nearby. Another large dust storm is spilling out of the giant Hellas impact basin in the Southern Hemisphere [lower right].

      Gardens on Mars? No, Just Rocks!
      NASA’s Mars Perseverance rover acquired this image of the area in front of it, showing the Serpentine Lake abrasion patch on the right-hand-side of the rock, with the Green Gardens sampling location on the left. The rover used its onboard Front Right Hazard Avoidance Camera A, and captured the image on Feb. 16, 2025 (sol 1420, or Martian day 1,420 of the Mars 2020 mission) at the local mean solar time of 16:45:19. NASA/JPL-Caltech Over the past week, Perseverance has been parked at a location called “Tablelands,” an area containing the “Serpentine Lake” abrasion patch acquired a few weeks ago. The Mars 2020 team has been diligently analyzing the data from the abrasion patch, and these findings led to the decision to return to Tablelands and attempt a sample at this location. Due to the disaggregated material thwarting our last sample attempt at “Cat Arm Reservoir,” the team was eagerly awaiting results from this sampling attempt at a target called “Green Gardens.”
      Then, very early Monday morning, the CacheCam images came down confirming that Perseverance had collected another core on Mars! The team will be working next on sealing this sample tube.
      NASA’s Mars Perseverance rover acquired this image using its onboard Sample Caching System Camera (CacheCam), located inside the rover underbelly. It looks down into the top of a sample tube to take close-up pictures of the sampled material and the tube as it’s prepared for sealing and storage. The material seen inside the coring bit is the Green Gardens sample. This image was acquired on Feb. 17, 2025 (sol 1420, or Martian day 1,420 of the Mars 2020 mission) at the local mean solar time of 19:16:24. NASA/JPL-Caltech Tablelands, the rock from which the Green Gardens core comes, is exciting to the Science Team because it contains serpentine minerals. These serpentine minerals likely formed several billion years ago when water interacted with rocks before Jezero crater formed. Water altered the minerals originally present in the rock into serpentine, which is often green in color. This characteristic green color is why the team chose the name “Green Gardens” for this sample target. These minerals are especially exciting because their structure and composition can tell us about the history of water on Mars. The formation of serpentine on Earth can support microbial communities, and the same might have been true on Mars. A sample like this from the Jezero crater rim is an important piece of the puzzle to Jezero’s watery past!
      Perseverance is planning to conclude its time at Serpentine Lake with more science observations of the Tablelands outcrop. These measurements could include a reexamination of the Serpentine Lake abrasion patch and analysis of the tailings pile produced by the Green Gardens drill. After snaking around this area for a couple weeks, our next drives will take us further down the slope of the crater rim. We’ll head toward our next stop at a site called “Broom Point,” where more exciting discoveries await!

      This NASA/ESA Hubble Space Telescope reveals clouds of gas and dust near the Tarantula Nebula, located in the Large Magellanic Cloud about 160,000 light-years away.ESA/Hubble & NASA, C. Murray The universe is a dusty place, as this NASA/ESA Hubble Space Telescope image featuring swirling clouds of gas and dust near the Tarantula Nebula reveals. Located in the Large Magellanic Cloud about 160,000 light-years away in the constellations Dorado and Mensa, the Tarantula Nebula is the most productive star-forming region in the nearby universe, home to the most massive stars known.
      The nebula’s colorful gas clouds hold wispy tendrils and dark clumps of dust. This dust is different from ordinary household dust, which may include bits of soil, skin cells, hair, and even plastic. Cosmic dust is often comprised of carbon or of molecules called silicates, which contain silicon and oxygen. The data in this image was part of an observing program that aims to characterize the properties of cosmic dust in the Large Magellanic Cloud and other nearby galaxies.
      Dust plays several important roles in the universe. Even though individual dust grains are incredibly tiny, far smaller than the width of a single human hair, dust grains in disks around young stars clump together to form larger grains and eventually planets. Dust also helps cool clouds of gas so that they can condense into new stars. Dust even plays a role in making new molecules in interstellar space, providing a venue for individual atoms to find each other and bond together in the vastness of space.

      6 Min Read NASA’s PUNCH Mission to Revolutionize Our View of Solar Wind 
      Earth is immersed in material streaming from the Sun. This stream, called the solar wind, is washing over our planet, causing breathtaking auroras, impacting satellites and astronauts in space, and even affecting ground-based infrastructure. 
      NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission will be the first to image the Sun’s corona, or outer atmosphere, and solar wind together to better understand the Sun, solar wind, and Earth as a single connected system.  
      Launching no earlier than Feb. 28, 2025, aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California, PUNCH will provide scientists with new information about how potentially disruptive solar events form and evolve. This could lead to more accurate predictions about the arrival of space weather events at Earth and impact on humanity’s robotic explorers in space. 
      “What we hope PUNCH will bring to humanity is the ability to really see, for the first time, where we live inside the solar wind itself,” said Craig DeForest, principal investigator for PUNCH at Southwest Research Institute’s Solar System Science and Exploration Division in Boulder, Colorado.

      The PUNCH mission’s four suitcase-sized satellites have overlapping fields of view that combine to cover a larger swath of sky than any previous mission focused on the corona and solar wind. The satellites will spread out in low Earth orbit to construct a global view of the solar corona and its transition to the solar wind. They will also track solar storms like coronal mass ejections (CMEs). Their Sun-synchronous orbit will enable them to see the Sun 24/7, with their view only occasionally blocked by Earth.  
      Typical camera images are two dimensional, compressing the 3D subject into a flat plane and losing information. But PUNCH takes advantage of a property of light called polarization to reconstruct its images in 3D. As the Sun’s light bounces off material in the corona and solar wind, it becomes polarized — meaning the light waves oscillate in a particular way that can be filtered, much like how polarized sunglasses filter out glare off of water or metal. Each PUNCH spacecraft is equipped with a polarimeter that uses three distinct polarizing filters to capture information about the direction that material is moving that would be lost in typical images.  
      “This new perspective will allow scientists to discern the exact trajectory and speed of coronal mass ejections as they move through the inner solar system,” said DeForest. “This improves on current instruments in two ways: with three-dimensional imaging that lets us locate and track CMEs which are coming directly toward us; and with a broad field of view, which lets us track those CMEs all the way from the Sun to Earth.” 
      All four spacecraft are synchronized to serve as a single “virtual instrument” that spans the whole PUNCH constellation. 
      Crews conduct additional solar array deployment testing for NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) satellites at Astrotech Space Operations located on Vandenberg Space Force Base in California on Wednesday, Jan. 22, 2025. USSF 30th Space Wing/Alex Valdez The PUNCH satellites include one Narrow Field Imager and three Wide Field Imagers. The Narrow Field Imager (NFI) is a coronagraph, which blocks out the bright light from the Sun to better see details in the Sun’s corona, recreating what viewers on Earth see during a total solar eclipse when the Moon blocks the face of the Sun — a narrower view that sees the solar wind closer to the Sun. The Wide Field Imagers (WFI) are heliospheric imagers that view the very faint, outermost portion of the solar corona and the solar wind itself — giving a wide view of the solar wind as it spreads out into the solar system.   
      “I’m most excited to see the ‘inbetweeny’ activity in the solar wind,” said Nicholeen Viall, PUNCH mission scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “This means not just the biggest structures, like CMEs, or the smallest interactions, but all the different types of solar wind structures that fill that in between area.” 
      When these solar wind structures from the Sun reach Earth’s magnetic field, they can drive dynamics that affect Earth’s radiation belts. To launch spacecraft through these belts, including ones that will carry astronauts to the Moon and beyond, scientists need to understand the solar wind structure and changes in this region. 
      Building Off Other Missions 
      “The PUNCH mission is built on the shoulders of giants,” said Madhulika Guhathakurta, PUNCH program scientist at NASA Headquarters in Washington. “For decades, heliophysics missions have provided us with glimpses of the Sun’s corona and the solar wind, each offering critical yet partial views of our dynamic star’s influence on the solar system.” 
      When scientists combine data from PUNCH and NASA’s Parker Solar Probe, which flies through the Sun’s corona, they will see both the big picture and the up-close details. Working together, Parker Solar Probe and PUNCH span a field of view from a little more than half a mile (1 kilometer) to over 160 million miles (about 260 million kilometers). 
      Additionally, the PUNCH team will combine their data with diverse observations from other missions, like NASA’s CODEX (Coronal Diagnostic Experiment) technology demonstration, which views the corona even closer to the surface of the Sun from its vantage point on the International Space Station. PUNCH’s data also complements observations from NASA’s EZIE (Electrojet Zeeman Imaging Explorer) — targeted for launch in March 2025 — which investigates the magnetic field perturbations associated with Earth’s high-altitude auroras that PUNCH will also spot in its wide-field view.

      NASA’s Goddard Space Flight Center Conceptual Image Lab As the solar wind that PUNCH will observe travels away from the Sun and Earth, it will then be studied by the IMAP (Interstellar Mapping and Acceleration Probe) mission, which is targeting a launch in 2025. 
      “The PUNCH mission will bridge these perspectives, providing an unprecedented continuous view that connects the birthplace of the solar wind in the corona to its evolution across interplanetary space,” said Guhathakurta. 
      The PUNCH mission is scheduled to conduct science for at least two years, following a 90-day commissioning period after launch. The mission is launching as a rideshare with the agency’s next astrophysics observatory, SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer).  
      “PUNCH is the latest heliophysics addition to the NASA fleet that delivers groundbreaking science every second of every day,” said Joe Westlake, heliophysics division director at NASA Headquarters in Washington. “Launching this mission as a rideshare bolsters its value to the nation by optimizing every pound of launch capacity to maximize the scientific return for the cost of a single launch.” 
      The PUNCH mission is led by Southwest Research Institute’s offices in San Antonio, Texas, and Boulder, Colorado. The mission is managed by the Explorers Program Office at NASA Goddard for NASA’s Science Mission Directorate in Washington.

      Hubble Spies a Spiral That May Be Hiding an Imposter

      The sparkling spiral galaxy gracing this NASA/ESA Hubble Space Telescope image is UGC 5460, which sits about 60 million light-years away in the constellation Ursa Major. This image combines four different wavelengths of light to reveal UGC 5460’s central bar of stars, winding spiral arms, and bright blue star clusters. Also captured in the upper left-hand corner is a far closer object: a star just 577 light-years away in our own galaxy.
      UGC 5460 has hosted two recent supernovae: SN 2011ht and SN 2015as. It’s because of these two stellar explosions that Hubble targeted this galaxy, collecting data for three observing programs that aim to study various kinds of supernovae.
      SN 2015as was as a core-collapse supernova: a cataclysmic explosion that happens when the core of a star far more massive than the Sun runs out of fuel and collapses under its own gravity, initiating a rebound of material outside the core. Hubble observations of SN 2015as will help researchers understand what happens when the expanding shockwave of a supernova collides with the gas that surrounds the exploded star.
      SN 2011ht might have been a core-collapse supernova as well, but it could also be an impostor called a luminous blue variable. Luminous blue variables are rare stars that experience eruptions so large that they can mimic supernovae. Crucially, luminous blue variables emerge from these eruptions unscathed, while stars that go supernova do not. Hubble will search for a stellar survivor at SN 2011ht’s location with the goal of revealing the explosion’s origin.
