This week’s image is from NASA’s Astronomy Picture of the Day. It is a composite image from the James Webb Space Telescope (JWST) and the Hubble Space Telescope showing Messier 64 (M64), which is a spiral galaxy about 17 million light-years away.

Here is a little more information from NASA explaining what you are seeing here:

Sometimes where Hubble finds darkness, Webb sees light. An example is today’s composite images of Messier 64 (M64), a nearby spiral galaxy of many names. The dark band of dust partially blocking its bright core earned it the moniker “the Black Eye Galaxy.” Webb’s Mid-InfraRed Instrument (MIRI) sees that dust, shown in red, as it absorbs and re-emits light from surrounding newborn stars. These young stars are embedded in pink star-forming regions in the secondary Hubble-only image. M64’s inner and outer gas regions counter-rotate, creating regions of increased star formation where the two gas “currents” meet and compress. A merger between M64 and a smaller galaxy was likely the cause of the opposing motion of the outer gas. Spiral galaxies were once thought to have peaceful histories. M64 was key evidence that spiral galaxies, including the Milky Way, can and do experience mergers. Webb’s view of M64 will tell astronomers about the structure, motion, and composition of the galaxy’s dust and add context to the galaxy’s merger history and evolution.

Talk about eerie. This week’s image is from the NASA/European Space Agency’s (ESA) Hubble Space telescope. The ghostly image shows nebula LHA 120-N44, or N44, which is about 160,000 light-years away. It is within the Large Magellanic Cloud that orbits our galaxy.

Here is more from NASA describing what you are seeing:

N44 is dominated by two features: a vast central void and a shell of dense, dusty gas. The central void is a ‘superbubble’ spanning roughly 210 by 140 light-years across. The glittering stars at the center of the void are responsible for its creation; through their powerful stellar winds and explosive supernovae, these stars expelled much of the gas from which they were born.

When the stars of N44’s central star cluster swept away this gas, the expelled gas compressed and formed a shell around the superbubble. New stars are forming in this compressed gas shell, making N44 an interesting target for astronomers who are using the nebula to study how stars form in this environment. Their goal is to understand how long it takes from the collapse of cold gas clouds into dense knots to the moment nuclear fusion ignites in the heart of a newborn star.

Pic of the Week: Galactic Gems

This week’s images of 16 galaxies are from a variety of NASA telescopes. The galaxies are generally sorted into three types – spiral, elliptical, and irregular. For example, the Milky Way galaxy is a spiral galaxy, whereas Centaurus A (Cen A above) is a giant elliptical galaxy and NGC 1569 (also above) is a compact dwarf irregular galaxy.

This week’s image is from the Hubble Space Telescope. It shows the dwarf irregular galaxy ESO 490-017 as a mist of stars in the upper center of the image (hence the term “irregular”). The galaxy is about 23 million light-years away and only 12,000 light years across, compared to the 100,000 light-year diameter of the Milky Way Galaxy. If you look carefully, you can spot a variety of regular galaxies in the background that blend in with the stars in the foreground.

House Budget Looking Better for NASA

The Planetary Society has provided a nice summary of where the NASA funding battle is at this moment. Here is its latest summary of events:

  • The House budget bill that includes NASA funding just cleared a key hurdle, advancing out of the Appropriations Committee. This is the first funding bill for FY 2027 to be released and reach this stage, establishing congressional intent and rejecting the worst of the Office of Management and Budget’s proposed cuts to NASA.
  • The bill keeps NASA funding flat with the currently enacted budget, but reprioritizes funding levels across the agency, including a 17% cut to Science to offset increases elsewhere.
  • A number of science missions proposed for cancellation by the OMB see their funding protected by this bill, including OSIRIS-APEX, New Horizons, and the Chandra X-Ray Observatory. New programs initiated by Administrator Isaacman that were absent from the OMB proposal, like Space Reactor-1 Freedom, also see their first dedicated mention in the proposal.
  • The full House still needs to vote on this, and the Senate is expected to release its own proposal within weeks. Congress will then work to develop full-year funding, in anticipation of the start of FY 2027 on Oct. 1, but will likely require a short-term funding patch, which comes with its own hurdles.

I recommend you read the entire statement, House Appropriators Advance Key NASA Funding Bill, to fully understand the rigors of this Hill battle. Fortunately, both the House and Senate continue to be supportive of NASA’s work and Administrator Isaacman’s new direction for Artemis. It helps to have someone full time at the helm of the agency.

I was especially pleased to read that missions such as New Horizons and the Chandra X-Ray Observatory are being saved and key programs like the James Webb Space Telescope and the Hubble Space Telescope are no longer facing drastic cuts. It is unfortunate that the White House was so willing to destroy generations of space-related work – what have been called the crown jewels of our space program.

The budget battle is not over, but we are seeing that when good legislators push back, good things can happen.
