There have been a lot - a LOT - of articles about the science of Monday's total solar eclipse.

But what about the magic?

An eclipse is a profoundly emotional experience. Here's how to make sure you get the most from it: just be there for it.

Comet 12P/Pons-Brooks is brightening and can be seen in the western sky after sunset with a good pair of binoculars and good viewing conditions (dark and clear).

Discovered in 1385, Comet Pons-Brooks returns every 71 years. Its ion tail, visible in deep camera exposures, is pushed by solar wind and points away from the Sun. The comet may brighten enough to be visible during the April 8 solar eclipse!

Here is another stunning pic of Comet 12P/Pons–Brooks, taken by Fritz Helmut Hemmerich on April 9.

Also shown below is the image taken by Dan Bartlett on March 30, to help see how the comet shape has evolved over the past 10 days as it approaches the Sun.

Comet 12P/Pons–Brooks is very low in the evening sky now as it approaches perihelion, which will occur on April 21.

Please see the rest of this thread for additional info on this comet.

PRESS RELEASE: https://www.seti.org/press-release/giant-volcano-discovered-mars
Giant Volcano Discovered on Mars

A deeply eroded giant volcano, active from ancient through recent times and with possible remnants of glacier ice near its base, had been hiding near Mars’ equator in plain sight. Its discovery points to an exciting new place to search for life, and a potential destination for future robotic and human exploration.

@setiinstitute There will be a talk about these Mars volcano findings in eastern Noctis Labyrinthus this afternoon given by Pascal Lee at 4:50 p.m. at . Here is Lee and Sourabh Shubham's abstract: https://www.hou.usra.edu/meetings/lpsc2024/pdf/2745.pdf

The NASA/Astrobotic Peregrine lunar landing mission, launched today, is experiencing an anomaly 😢

A propulsion anomaly has resulted in improper pointing of the spacecraft resulting in drop in power from the solar panels. An improvised maneuver was made to reorient the solar panels. The spacecraft is currently out of range of the ground station, fingers are crossed to check the status when it comes back in comm. view again.

Update #8 from Astrobotic on a possible cause of the propulsion system anomaly on the Peregrine spacecraft.

"A valve between the helium pressurant and the oxidizer failed to reseal after actuation during initialization. This led to a rush of high pressure helium that spiked the pressure in the oxidizer tank beyond its operating limit and subsequently ruptured the tank."

Not caused by launch vehicle.

The venerable Voyager 1 spacecraft is experiencing another glitch. Instead of sending science and engg. data, it is sending a 0101 bit pattern.

The problem has been narrowed down to the flight data system (FDS), which is not communicating properly with the telecom unit (TMU). A reboot did not help.

Stay tuned as NASA engrs work out a fix for this 1970's era computer, which has performed magnificently during its long 46-year journey to the planets and to outer space.

Confirmation today from the Voyager 1 team that the transmission received on Sunday contained science data from 2 of the 4 operating instruments - the plasma wave subsystem and the magnetometer. The other 2 instruments - the cosmic ray subsystem and the low energy charged particle instrument - require recalibration, which will be done in the coming weeks.

The delicate software operation is working as expected.

: This 3D image of Ryugu was put together by Dr. Brian May, astrophysicist and guitarist for the British rock band Queen. The top and bottom are inverted compared to how we usually show the asteroid, and this photo has Ryugu’s south pole at the image top. The Otohime Saxum, which is a large boulder, is clearly visible.

Also, check out
https://fosstodon.org/@AkaSci/111508327742645611
for a stereo image of asteroid Dinkinesh, put together by ... who else but Dr. Brian May.
Also, has some background on the naming of the asteroid and its moonlet, and the Lucy mission.
