The images released to celebrate the 25th anniversary of the Chandra X-ray Observatory are too beautiful to be visited only once. Above is another amazing image from the collection showing the Crab Nebula.

Here is a little more about this image from NASA:

This composite image features the remnant of a supernova explosion, which resembles a neon purple mushroom at the heart of a colorful web of veins and filaments. Known as the Crab Nebula, the heavily veined blue and red cloud of gas is set against the blackness of space. At the core of the nebula is a pulsar, a rotating neutron star emitting electromagnetic radiation. Here, the pulsar appears as a bright white dot sitting in a neon purple cloud. Surrounding the dot are white rings. These are created by particles driven away from the pulsar and colliding with gas in the nebula to produce X-rays. From this angle, the rings and purple cloud combine to resemble a mushroom cap. Completing the look of a mushroom is a thin mushroom stem emerging from the white dot. This is a narrow beam of particles blasting away from the pulsar.

And below is one more image, NGC 1850, with this narrative from NASA:

This composite image features a double star cluster, a blue-tinted cloud, and several neon purple dots. This double cluster is part of the Large Magellanic Cloud, a companion galaxy to the Milky Way. The bright, golden stars in the larger cluster fill the upper center of the image. The other cluster is much smaller and coincides with one of the neon purple circles located slightly above and to the right of the image’s center. This and the other purple circles are X-ray sources detected with Chandra. To our left of the combined cluster is a vertical streak of blue-tinted cloud. Extending beyond the upper and lower edges of the image, this section of cloud resembles wafting smoke from a cigarette.

Space Quote: Microscopic Life on Mars?

“Cheyava Falls is the most puzzling, complex, and potentially important rock yet investigated by Perseverance…On the one hand, we have our first compelling detection of organic material, distinctive colorful spots indicative of chemical reactions that microbial life could use as an energy source, and clear evidence that water — necessary for life — once passed through the rock. On the other hand, we have been unable to determine exactly how the rock formed and to what extent nearby rocks may have heated Cheyava Falls and contributed to these features.”

–Statement by Ken Farley, Perseverance project scientist of Caltech in Pasadena, regarding a recent finding by the Perseverance rover on Mars. The rock, labeled “Cheyava Falls,” may answer whether Mars was home to microscopic life in the distant past.

Pic of the Week: Celebrating Chandra’s 25th Anniversary

NASA’s Chandra X-ray Observatory is celebrating the 25th anniversary of the observatory, which means we get to view quite a few amazing images from over the years, such as the one above called the Bat Shadow.

Here is more from NASA on this image explaining the bat connection:

In this composite image, several pink and white stars gleam through murky cloud formations. These are young stars detected by Chandra. At our lower right, an opaque cloud resembling a veined slug rises out of a muddy brown mist. Blue and grey clouds with hints of brown stretch from our lower left, to our upper right. There, near the upper righthand corner, two long black triangles appear to burst from a central gleaming star. These triangles are in fact shadows from the young star, cast on distant blue and grey clouds. The eerie shape, reminiscent of the Batman call sign projected against a cloudy Gotham sky, has earned the phenomenon the nickname The Bat Shadow.

27th Annual International Mars Society Convention

Posted on by onespaceman2000

You still have time to sign up for the Mars Society’s 27th Annual International Mars Society Convention, happening from August 8-11 in Seattle, WA.

Some of the guests include:

  • Tiffany M. Morgan, Deputy Director of the Mars Exploration Program in NASA’s Science Directorate, who will give an address about “Exploring Mars Together, DRAFT Plan for a Sustainable Future for Science at Mars.”
  • Howard Hu, the Orion Program Director at NASA, who will give an address about “NASA’s Artemis plans for returning to the Moon and beyond,”
  • Brig. General (Ret.) Dr. S. Pete Worden, Chairman of the Breakthrough Prize Foundation, who will give an address about “Life in the Universe and Private Sector Space Science Initiatives.”
  • Dr. Alan Stern, a renowned planetary scientist and commercial astronaut, who will give an address about “The Other Red Planet” focusing on Pluto.

These are just a few of the names and presenters this year. You can also watch the presentations from prior conventions if you want to see what you missed.

Space Stories: Starliner Still Stuck, Space Walks Nixed, and ISS Artifacts Being Considered

Here are some recent stories of interest related to the International Space Station (ISS).

—WFLA.com: “Astronauts Remain in Space as Boeing’s Starliner Mission Exceeds 45-day Window at ISS“

Two astronauts aboard Boeing’s Starliner remain stuck in space as the mission exceeded its 45-day battery window being docked at the International Space Station. The capsule, which arrived at the space station on June 6, was initially approved to stay for up to 45 days but with no return date set, the astronauts’ stay has been “extended indefinitely,” NBC affiliate WESH reported. NASA and Boeing said the capsule’s batteries are performing well despite the extended stay. Tuesday marked 47 days since they’ve been at the ISS.

—Space.com: “NASA delays ISS Spacewalks Indefinitely to Investigate Spacesuit Coolant Leak“

NASA says its next spacewalk will be delayed indefinitely until engineers understand more about what caused a coolant leak on June 24. Tracy Dyson, a NASA astronaut, had a brief spacesuit leak a month ago while still in the hatch of the International Space Station (ISS). She and Mike Barrett had just opened the door for a 6.5-hour spacewalk for maintenance activities, when showers of ice particles erupted from a spacesuit connection to the ISS. The spacewalk was suspended, but the astronauts were never in any danger, NASA has emphasized.

—Collectspace.com: “NASA Looking at What Artifacts to Save from ISS Before 2030 Demise“

Two years after stating there were no plans to save artifacts from the destructive end of the International Space Station (ISS), NASA is now in the early stages of identifying what small parts of the orbiting laboratory to preserve. Agency officials on Wednesday (July 17) shared the preliminary details during a media briefing about the space station’s end of life in 2030 and the selection of SpaceX to build the vehicle that will move the massive complex out of orbit such that it mostly burns up in Earth’s atmosphere and plunge any surviving fragments into a remote area of the ocean.
