#PPOD: The Apollo 11 landing site is pictured here with the lunar module descent stage casting a shadow toward Little West crater, as imaged with the Orbiter High-Resolution Camera on India's Chandrayaan-2 from an altitude of 100 km on April 2, 2021. Credit: ISRO / Chandrayaan-2 / OHRC / JPMajor
For a dose of perspective: Even at the peak speed of the Parker Solar Probe (~180 km/sec), it would take more than 7,000 years to reach Alpha Centauri, the nearest star system.
#Euclid has hardware, software, data, and functional contributions by more than 100 institutions across #ESA member states, the USA, Canada, and Japan.
With the fully assembled #satellite currently undergoing final tests, and with the science computing ground segment on it's home stretch, we're seeing Euclid rapidly turning from hard- and software into a soon flying #astronomy data-producing #space mission!
No new info on the status of the Voyager 1 spacecraft, which since Sep 2023 has been sending a 1010 bit pattern instead of real data.
Several popular science outfits have been covering it lately. A bit flip in the FDS is suspected, but it is difficult to identify since the memory cannot be read back.
Several commands were sent yesterday to Voyager 1; responses will arrive 45 hours later tomorrow.
Wonder why they cannot overwrite all prog and data memory.
You've heard of a sound echo: Sound bounces off of a surface and reflects back, causing a delay.
Did you know that light echos are also a thing? If there is a flash of light from something like a supernova, that light can hit interstellar clouds of dust and then reflect back, giving you light from the original supernova but on a delay.
We can use this delayed light to learn about what kind of star blew up in the supernova.
Happy first anniversary, #NASAWebb! One year after beginning science operations, Webb is celebrating with a highly detailed image of the closest star-forming region to Earth. Peer deeper in the cloud: https://webbtelescope.pub/3JUoBTA
The Moon last night. Taken as four sets of red, green, blue and clear earthshine. Preprocessed in SolHAT, integrated in PixInsight, and composited in Photoshop.
The first #NASAWebb results from TRAPPIST-1 are in! Measurements of mid-infrared light from TRAPPIST-1 b indicate that the rocky Earth-sized planet is hot enough to bake pizza and is probably devoid of atmosphere. What does this mean? ➡️ https://webbtelescope.pub/3nlCcLc #space#astronomy#JWST#Trappist1b
Here's a picture of the Sun today that I took in hydrogen alpha. Compare that to a picture taken by NASA's Perseverance Rover a few hours ago with its Mastcam-Z. Sunspots 3216 (far-left) and 3214 (left) are visible on both. Even relative sizes check out.
