NASA's Parker Solar Probe Observes Sun Alongside Dozens of Observatories

NASA’s Parker Solar Probe completed its 15th close approach to the Sun on March 17, coming within 5.3 million miles of the scorching solar surface. The geometry of Parker’s latest orbit also placed it in direct view of Earth and several other Sun-observing spacecraft during its close encounter, providing unique scientific opportunities for collaborative observations from the ground and space.

Parker Solar Probe is humanity’s first mission to the sun. It orbits directly through the solar atmosphere–the corona–closer to the surface than any human-made object has ever gone. While facing brutal heat and radiation, the mission will reveal fundamental science behind what drives the solar wind, the constant outpouring of material from the sun that shapes planetary atmospheres and affects space weather near Earth.

Parker Solar Probe is part of NASA’s Living With a Star Program to explore aspects of the connected sun-Earth system that directly affect life and society.

Almost Touching: The Milky Way & The Swedish-ESO Telescope

Almost Touching: The Milky Way & The Swedish-ESO Telescope


Night image of the Swedish-ESO Telescope with an overall grey and dark blue color. The telescope is a big antenna seen sideways, taking up most of the left part of the image. To the right of the telescope the Milky Way dominates the sky and contains dark and bright areas. The Chilean mountains shape the horizon above the ground in the lower part of the image. This Picture of the Week shows a beautiful meeting between the Swedish–ESO Submillimetre Telescope (SEST) and the Milky Way, apparently almost touching each other. This shot was taken at the European Southern Observatory’s La Silla Observatory, located on the outskirts of the Chilean Atacama Desert, at an altitude of 2400 meters.

Light and darkness shape the Milky Way as it stretches across the night sky. The dark patches are dust clouds blocking the light behind them, coming from millions of stars in the central region of our galaxy.

Portrait of a Galactic Jellyfish: Galaxy JW100 | Hubble

Portrait of a Galactic Jellyfish: Galaxy JW100 | Hubble


The galaxy JW100 features prominently in this image from the NASA/European Space Agency Hubble Space Telescope, with streams of star-forming gas dripping from the disc of the galaxy like streaks of fresh paint. These tendrils of bright gas are formed by a process called ram pressure stripping, and their resemblance to dangling tentacles has led astronomers to refer to JW100 as a ‘jellyfish’ galaxy. It is located in the constellation Pegasus, over 800 million light-years away.

Image Description: A thin spiral galaxy is seen edge-on in the lower right. Its bulge and arms are very bright, mixing reddish and bluish light. Patchy blue trails extend below it, resembling tentacles, made from star-forming regions. Six small, reddish elliptical galaxies are scattered around. A very large elliptical galaxy with two cores sits by the top of the frame.

Ram pressure stripping occurs when galaxies encounter the diffuse gas that pervades galaxy clusters. As galaxies plough through this tenuous gas it acts like a headwind, stripping gas and dust from the galaxy and creating the trailing streamers that prominently adorn JW100. The bright elliptical patches in the image are other galaxies in the cluster that hosts JW100.

As well as JW100’s bright tendrils, this image also contains a remarkably bright area of diffuse light towards the top of this image which contains two bright blotches at its core. This is the core of IC 5338, the brightest galaxy in the galaxy cluster, known as a cD galaxy. It’s not unusual for cD galaxies to exhibit multiple nuclei, as they are thought to grow by consuming smaller galaxies, the nuclei of which can take a long time to be absorbed. The bright points of light studding its outer fringes are a rich population of globular clusters. 

This observation took advantage of the capabilities of Hubble’s Wide Field Camera 3, and is part of a sequence of observations designed to explore star formation in the tendrils of jellyfish galaxies. These tendrils represent star formation under extreme conditions, and could help astronomers understand the process of star formation elsewhere in the universe.

Pulsar PSR B1509-58: Multiwavelength View | NASA Chandra X-ray Observatory


This image shows multiwavelength perspectives on the pulsar PSR B1509-58. The 2 Micron All-Sky Survey (2MASS) infrared images shows a large area of the sky around the pulsar. The SuperCOSMOS optical image is closer in and shows a surrounding cloud of gas. Chandra X-ray data show the effects of an energetic wind powered by the pulsar. The X-ray emission results from very energetic electrons spiraling in a magnetic field. Finger-like structures extend to the upper right and energize knots of material in the gas cloud. The Molonglo Observatory Synthesis Telescope (MOST) radio data shows the larger structure of the supernova remnant SNR G320.4-1.2 that encircles the pulsar PSR B1509.

Tropical Cyclone Freddy: Longest-lived on Record: 5+ Weeks! | NASA

Tropical Cyclone Freddy: Longest-lived on Record: 5+ Weeks | NASA

Tropical Cyclone Freddy lasted more than five weeks. Once a very powerful Category 5 cyclone, Freddy first made landfall along the east coast of Madagascar on February 21st, 2023, just north of the town of Mananjary as a Category 3 cyclone with average winds reported at 130 km/h (~81 mph) with gusts up to 180 km/h (~112 mph). After crossing over Madagascar, Freddy continued westward over the Mozambique Channel before making landfall again and for the first time along the east coast of Mozambique just south of Vilankulos as a moderate tropical storm with sustained winds estimated at 50 mph. 

However, despite being weaker at landfall, Freddy has resulted in widespread flooding across parts of Mozambique due to the storm stalling out near the coast after making landfall. Incredibly, Freddy then drifted back out over the Mozambique Channel, nearly making landfall again along the southwest coast of Madagascar, before changing direction, re-intensifying, weakening, re-intensifying one last time, and making landfall for the 2nd time in Mozambique as a Category 1 cyclone near Quelimane with sustained winds reported at 90 mph on the 11th of March.


The Indian Ocean is the third-largest of the world's five oceanic divisions at ~19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica. [Wikipedia]

The Moon's South Pole: Malapert Massif | NASA Artemis III Landing Site Candidate

The Moon's South Pole: Malapert Massif | NASA Artemis III Landing Site Candidate


Malapert massif (informal name) is thought to be a remnant of the South Pole—Aitken basin rim, which formed more than 4 billion years ago. The 5-kilometer tall Malapert Mountain is a peak that is perpetually visible from the Earth. It could serve as a radio relay station when suitably equipped. More recently, this magnificent peak (lower left) was selected as an Artemis 3 candidate landing region. Image is 25 kilometers wide in the center, Narrow Angle Camera M1432398306LR.

NASA's Lunar Reconnaissance Orbiter camera shuttered this view on March 3, 2023, when the spacecraft was about 170 kilometers beyond Shackleton crater (sub-spacecraft point was 84.10°S, 129.1°E) looking towards the nearside. From this viewpoint, we see the back side of Malapert massif assuming an Earth-centric reference. The Artemis 3 candidate landing region is partially visible from this viewpoint.

Imagine the view from the summit; it rises more than 5000 meters  (16,400 feet) above its base. Off in the distance, you could see a 3500 meter (11,480 feet) tall cliff. One could argue that the sheer grandeur of this region makes it a prime candidate. However, then again, a landing here might be too exciting?

Tahira Allen: Portrait of a Storyteller | NASA's Digital Lead for Planetary Science

Tahira Allen: Portrait of a Storyteller | NASA's Digital Lead for Planetary Science


“Even if the people around you don’t look like you, that doesn’t mean you don’t have a place at the table.”

Tahira Allen is a lot of things—Turkish, African American, millennial, young, professional—but shy is not one of them. As one of the Social Media Specialists for the agency, Allen uses her identity as a way to relate with the audiences she communicates with.

“My identity, being as mixed as it is, allows me to be especially open-minded and inclusive of niche communities and cultures,” says Allen. “Space is an international arena, and the science and technological feats and discoveries are not shut off to the U.S. — they are global.”

As a communicator and storyteller for the agency, Allen’s job is to bring space to the public in an approachable way. One of Allen’s main goals is to show our audiences that the people behind NASA are just that—“just everyday people who laugh and enjoy the same things they do!”

Allen’s favorite part about being the voice of NASA is being at the center of ground-breaking discoveries: “I get to take these amazing topics, merge them with everyday conversations and make them relatable.”

Everyday, Allen is inspired by the increasing amount of diversity she sees in the workforce—but she encourages young women of different heritages to “take that moonshot” and put themselves out there.  

And although Allen thrives in digital mediums, she also urges her audiences to reach out to unfamiliar faces, forge personal bonds and embrace human stories.

“Really, at the end of the day all of my identities—be it Turkish, African American, only child, Southern female millennial—have taught me the value of family, human inclusivity and being a strong, independent woman.”

“Starting to host live broadcasts [brought up] so many emotions: terrified, excited, proud.

And people have told me, ‘Oh my goodness, I feel like I would freeze up when the camera’s on,’ but that was the most natural position for me because I felt, just a little bit, like I was back on stage, cheerleading. You’re standing on the stage, the lights are off, you're in your head. And then the lights turn on, the music drops, and you’re on a world stage in front of thousands of people doing an incredibly difficult three-minute routine and who knows, you might even be injured right now, but you don't have an option. When those lights and that music comes on, it's almost like something bigger than yourself takes over and you just have to go.

And that is the exact same feeling when they're counting you down for a live broadcast: “3, 2, 1. Hello, welcome to NASA. My name is Tahira Allen!” Before something like that happens, I am terrified. I am sitting here thinking, what is about to come out of my mouth? But just like with cheer, whatever you do, you keep moving. I don't know what's going to come out my mouth. But I need to keep talking and just embrace fear. Embrace being uncomfortable.

…You cannot grow without approaching the fear, embracing the fear, and then pushing past it."

Star Cluster Messier 55 | Hubble Space Telescope

Star Cluster Messier 55 | Hubble Space Telescope


This image shows just a portion of M55, the star cluster as a whole appears spherical because the stars’ intense gravitational attraction pulls them together. Hubble’s clear view above Earth’s atmosphere resolves individual stars in this cluster. Ground-based telescopes can also resolve individual stars in M55, but fewer stars are visible.

The smaller, ground-based image (lower left) taken by the Digital Sky Survey illustrates the area of Messier 55 that Hubble observed.

A starchart that shows the location of M55 in the constellation Sagittarius above the southern horizon in August at 10 pm.

Even the great observer Charles Messier had trouble seeing this globular cluster when building his Catalog of Nebulae and Star Clusters. It was originally spotted in 1752 by a French astronomer in what is now South Africa, but it took until 1778 for Messier to catalog it.

This is because, while Messier 55 is large and reasonably bright, it is lacking a dense core and many of its stars are quite faint, making it hard to observe in non-optimal conditions.

For northern observers M55 sits low in the sky, so the view is hampered by a thicker layer of atmosphere, as well as water vapor and light pollution. This hindered Messier’s view from his Paris observatory. When he cataloged it, Messier noted that “its light is even and does not appear to contain any star.”

Though this image shows just a portion of M55, the cluster as a whole appears spherical because the stars’ intense gravitational attraction pulls them together. Hubble’s clear view above Earth’s atmosphere resolves individual stars in this cluster. Ground-based telescopes can also resolve individual stars in M55, but fewer stars are visible.

Even in skies with low light pollution, viewed through binoculars, the cluster will only appear as a round hazy patch. Small telescopes can begin to resolve individual stars in M55, while larger aperture telescopes will pick out low magnitude stars easily. The star cluster is found in the southern part of the constellation Sagittarius and is easiest to spot in August.

The globular cluster is about 20,000 light-years away and has a diameter of about 100 light-years. It contains an estimated 100,000 stars with 55 variable stars whose brightness changes.

This star chart for M55 represents the view from mid-northern latitudes for the given month and time.
