This week’s image, released late last year, comes from NASA’s James Webb Space Telescope (JWST). Messier 104 (M104), called the Sombrero galaxy, shines in all its blueness. It is about 31 million light-years away. It would have been interesting to see this galaxy from above (or below, for that matter).

Here is more about the galaxy from NASA:

In Webb’s mid-infrared view of the Sombrero galaxy, also known as Messier 104 (M104), the signature, glowing core seen in visible-light images does not shine, and instead a smooth inner disk is revealed. The sharp resolution of Webb’s MIRI (Mid-Infrared Instrument) also brings into focus details of the galaxy’s outer ring, providing insights into how the dust, an essential building block for astronomical objects in the universe, is distributed. The galaxy’s outer ring, which appeared smooth like a blanket in imaging from NASA’s retired Spitzer Space Telescope, shows intricate clumps in the infrared for the first time.

Note: Below is another view of the galaxy from the Hubble Space Telescope.

This week’s image comes from NASA’s Juno spacecraft, which captured these images of Jupiter’s north polar region. The spacecraft came within 6,800 miles of the clouds you see.

Launched in August 2011, the Juno spacecraft has been studying Jupiter since 2016 to better understand the origin and evolution of the planet.

Pic of the Week: The Glow of Cassiopeia A

This week’s image was taken by the James Webb Space Telescope (JWST) and highlighted in Scientific American magazine. It shows a colorful supernova remnant called Cassiopeia A, which is about 350 light-years away.

The magazine article notes:

The recent photographs are helping scientists answer some of their most pressing questions about supernovae, such as which types of stars explode in which ways and how exactly those outbursts unfold. “There is a lot of complicated but beautiful physics in understanding how this explosion takes place,” says Purdue University astronomer Danny Milisavljevic, who led the team behind the JWST images…

Astronomers will keep studying Cassiopeia A, although their success makes them eager to turn JWST’s eyes toward some of the other roughly 400 identified supernova remnants in our galaxy. Getting a larger sample will help researchers connect differences in how remnants look and evolve to differences among the stars that produced them.

Pic of the Week: Successful Launch of the New Glenn Rocket

Earlier today, Blue Origin’s New Glenn rocket safely made its way into the Earth’s orbit from its launch pad at the Cape Canaveral Space Force Station in Florida. The only piece of the mission that fell short was the loss of the booster that should have landed on a barge in the Atlantic Ocean.

After the successful launch, Blue Origin’s CEO Dave Limp stated:

I’m incredibly proud New Glenn achieved orbit on its first attempt…We knew landing our booster, So You’re Telling Me There’s a Chance, on the first try was an ambitious goal. We’ll learn a lot from today and try again at our next launch this spring. Thank you to all of Team Blue for this incredible milestone.

Even with the lost booster, the rocket launch has proven that the US space industry may soon have another reliable competitor to challenge SpaceX, which is good new for everyone.

Pic of the Week: Icelandic Volcanic Fissure

This week’s image comes from NASA’s Earth Observatory. It is an image from last November showing a volcanic fissure on Iceland’s Reykjanes peninsula not far from the country’s capital, Reykjavík

Here is more about the image from the NASA site:

The image…shows lava coming from an eruptive fissure near Stóra Skógfell peak, along the Sundhnúkur crater row—a similar location to the February 2024 eruption. This natural color scene, acquired by the OLI-2 (Operational Land Imager-2) on Landsat 9 on November 24, is overlaid with an infrared signal to help distinguish the lava’s heat signature. A plume of gas, consisting primarily of sulfur dioxide, streamed from the lava, although the eruption did not affect flights to and from Iceland.

The lava flowed east and west from the fissure, rather than toward the town of Grindavík. The Icelandic National Broadcasting Service reported that the latest event forced the evacuation of some of the town’s residents and the Blue Lagoon resort, a geothermal spa. A tongue of lava flowed over the car park of the spa, enveloping a small service building located there.

The Reykjanes peninsula eruption is the seventh in a series of events that began in December 2023. As of November 26, 2024, the Blue Lagoon was closed to the public, but lava movement toward the spa had slowed.

Note: Another image from NASA’s Earth Observatory is also very relevant this week. The image below shows the Los Angeles fires that are still burning. This particular image shows the Eaton fire, which erupted on the evening of January 7 in Altadena, located north of downtown Los Angeles.
