Through a gravitational lens effect caused by a massive foreground cluster of galaxies (MACS J0138), multiple images of a perfectly aligned background galaxy (MRG-M0138) are created, including the supernova Encore it hosts. This image was captured by JWST in 2023.

I have restarted work on the GE NEP crewed Mars mission post. After all the turmoil this past month, it's like meeting with an old friend.

My goal is to finish the post by Halloween.

🟠 Caltech researchers have developed a new simulation of the hydrological cycle on Jupiter, modeling how water vapor condenses into clouds and falls as rain throughout the giant planet's swirled, turbulent atmosphere.

This photo from the Perseverance rover captured in early March, may be my favorite Mars image from this year.

It shows Mars' smaller moon Deimos over the hills of the Nili Planum region in the dark skies before dawn. 🔭

A picture of Mars taken during astronomical twilight (the sun was 13° below the horizon). It shows a dimly lit reddish landscape with some hills at the horizon. Deimos, Mars' smaller moon shines with a small halo in the pale sky above.

Today, Percy checks out the calibration target of her SHERLOC instrument, including a slice of a Martian meteorite and five spacesuit materials.

The calibration target with, at left, five swatches of spacesuit materials that scientists are studying as they degrade. The first sample at top is polycarbonate for use in a helmet visor; inscribed with the address of the fictional detective Sherlock Holmes, it doubles as a geochache for the public. Other materials in the left row, from top: Vectran; Ortho-Fabric; Teflon; coated Teflon. Right row, from top: aluminum gallium nitride on sapphire; a quartz diffuser; a slice of Martian meteorite; a maze for testing laser intensity; a separate aluminum gallium nitride on sapphire with different properties.

The Changing Ion Tail of Comet Lemmon

Credit: Victor Sabet & Julien De Winter
www.star.ucl.ac.uk/~apod/apod/a... 🧪🔭

Five shots side-by-side capturing Comet Lemmon at different times, illustrating how a comet tail might change. The ion tail of Comet C/2025 A6 (Lemmon) has been changing markedly, as detailed in the featured image sequenced over five days between September 25 and October 3 (left to right) from Texas, USA. On some days, the comet's ion tail was relatively more complex than other days. Reasons for tail changes include the rate of ejection of material from the comet's nucleus, the strength and complexity of the passing solar wind, and the rotation rate of the comet. Sometimes, over the course of a week, apparent differences even result from a change of perspective from the Earth. In general, a comet's ion tail will point away from the Sun, as gas expelled is pushed out by the Sun's wind. Comet Lemmon is still inbound and brightening, passing nearest the Earth on October 21 and nearest the Sun on November 8.

I think Perseverance may have spotted interstellar comet 3I/Atlas last night from Mars!

After stacking 20 images from Mastcam-Z, I found a faint smudge of light in the constellation Corona Borealis close to the location where the comet was expected. 🔭

image of the night sky showing a starfield with several dark and bright stars that are quite elongated due to the long exposure time.

the stars of the constellation corona borealis are annotated in green. a faint smudge, perhaps comet 3I/Atlas is marked with a red circle.
