Opportunity holds record for most sols(Martian days)spent on Mars. It completed staggering 5,111 sols before massive dust storm permanently cut off its power 2018​.

.

Operational statistics for top Mars rovers demonstrate their longevity:

Opportunity:5,111 sols(2004–18)

Curiosity:~4,900+sols(Active since 2012,& still exploring)

Perseverance:~1,850+sols(Active since 2021)

Spirit:2,208 sols(Active 2004–10)

This is an RGB color-composite made from images taken by NASA's Opportunity rover on May 6, 2004

This glowing ring is RCW 86, the remnant of an 2000 year old supernova explosion observed by multiple NASA telescopes.

NASA’s IXPE telescope recently studied a section of the remnant where scientists believe the expanding shockwave slammed into the edge of a low-density “cavity” in space, creating the reflected shock effect visible in purple.

The image combines data from:

NASA’s IXPE

Chandra X-ray Observatory

ESA’s XMM-Newton telescope

NOIRLab starfield data

Yellow shows lower-energy X-rays, while blue represents higher-energy X-rays. The result looks almost like a cosmic painting across space.

A multispectral color image of some part of Mars. As with most of Mars, there are a whole lot of craters. Notably, a bunch of the craters in the lower left look like they have comet tails stretching out long across the surface.

A lot of the craters have bright rims on the left side of them and dark floors. Some features resembling rivers are etched across the lower smoother dark part that only has small craters. This doesn't mean they were ever rivers. The writer of this text doesn't know enough about terrestrial imaging to give information about what the various colors mean.

The darker areas tend to be blues and purples while the lighter areas tend to be yellows.

The top image is a view from the Cassini spacecraft, looking back across billions of miles of space through the rings of Saturn. That tiny, bright blue pixel pointed out by the arrow is Earth.

This is Carl Sagan’s famous "Pale Blue Dot." Every human who ever lived, every war fought, every triumph, and everything you have ever known took place on that single, fragile pixel suspended in a vast cosmic dark. From Saturn's perspective, our entire world is just a stray speck of dust caught in a sunbeam.

The bottom image is almost the exact opposite. That tiny glowing speck in the center is "Single Atom in an Ion Trap," a famous, award-winning photograph captured by physicist David Nadlinger at the University of Oxford.

A single, positively charged strontium atom suspended between those two metal electrodes. It is held near-motionless by electric fields and illuminated by a blue-violet laser. The atom absorbs and re-emits the laser light so rapidly that a standard camera can actually capture its glow on film. It is a single basic building block of matter, made visible to the human eye with a Canon 5D Mark II with a long exposure.

​A new neural-net analysis of faint stars observed by TESS just identified another 10,090 potential planets!

When they're confirmed (and most of them probably will be), they will more than double the number of known worlds beyond Earth.

.

To date, astronomers have confirmed the existence of just under 6,300 exoplanets. New research could more than double that number, adding a potential 10,000 new planets in one fell swoop.

Yes, that’s right. A 1 with 4 zeros.

The T16 project has announced the discovery of 10,091 exoplanet candidates observed by NASA’s Transiting Exoplanet Survey Satellite (TESS). Since 2018, the all-sky survey has been monitoring more than 200,000 nearby stars using the transit method, which detects the faint dip in a star’s light when a planet crosses in front of it. Astronomers typically require 3 dips to be sure that what they’re seeing is actually a planet and not a one-off event such as an asteroid or comet in that distant star system.

The T16 project analyzed the light curves of more than 54 million stars observed during the first year of the TESS mission. The project’s analysis technique allowed it to search for planets around stars up to 16 times fainter than TESS typically searches, drastically increasing the field of discovery.

.

Their pipeline detected 11,554 planet candidates. Of those, 1,052 of those had been detected previously and 411 only had one transit—not enough to confirm a planet.

That leaves 10,091 potential new planets. That’s more than were detected in the entirety of NASA’s Kepler mission and its follow-on K2 and more than double the existing planet candidates from TESS that await confirmation. These discoveries will be published in the Astrophysical Journal Supplement.

All of the new planet candidates orbit their stars quickly, with orbital periods between 12 hours and 27 days. Although most of the stars that TESS observes are smaller and cooler than the Sun, those close orbits likely mean that most of those planets are far too hot to be habitable.​
