Maintaining good overall health is key to living a long life, but we may want to particularly focus on the state of our brain and immune system

The European Southern Observatory has captured the clearest images yet of the interstellar visitor 3I/ATLAS as it moves inward through the solar system.

We now have the ability to rapidly assess the death toll of climate change after extreme heat – a first-of-its-kind analysis has shown that it nearly tripled the death toll from the most recent European heatwave

If you know where to look, you can see a thermonuclear explosion from a white dwarf star.

Does the Milky Way always rise between these two rocks?

Astronomers have made a breakthrough by using 25 year old Hubble images to investigate a potential "rogue planet" drifting through space without a host star. When a brief gravitational microlensing event occurred in 2023, researchers discovered Hubble had photographed the same location in 1997, creating an unprecedented quarter century baseline. Finding no stellar companion in the archival data strengthened evidence for a rogue planet with mass between Earth and Saturn, demonstrating the scientific value of space telescope archives for studying these elusive worlds wandering the Galaxy alone.

Some of the most powerful supercomputers in the world are designed to simulate complex astrophysical processes, like what's happening inside a giant star as it's going supernova. But researchers have developed a new machine learning algorithm that was able to accurately simulate galaxy evolution with fewer computer resources and dramatically more quickly than a supercomputer, which could take years to fully process.

Astronomers once wondered if the Universe might one day collapse in on itself in a Big Crunch, but the discovery of dark energy suggested that the expansion of the Universe would accelerate, removing that possibility. New data from the Dark Energy Spectroscopic Instrument suggests that dark energy might be changing in strength over time, maybe even going negative. If that result holds, are we due for a Big Crunch? And how long would it take?

Continuing the Quest for Clays NASA’s Mars Perseverance rover acquired this image showing the target “Jigging Cove,” named by Make-A-Wish participant Madeline, located in the center of the image. Perseverance used its Left Mastcam-Z camera, one of a pair of cameras located high on the rover’s mast, to capture the image on June 27, 2025 (Sol 1547, or Martian day 1,547 of the Mars 2020 mission) at the local mean solar time of 11:26:04.

For the past month and a half, Perseverance has been exploring the Krokodillen plateau in search of clay-bearing rocks. An earlier blog discussed that these rocks could hold clues to Mars’ watery past, and Perseverance has been exploring multiple potential locations to find a suitable target to sample. When a coring target could not be found at the previous outcrop, the Science Team decided to return to the “Main Topsail” locality. In a single drive to this area, Perseverance drove 411.7 meters (1,350.7 feet, or just over a quarter mile) — the longest driving distance ever accomplished by a robotic vehicle on another planet. Go, Percy, go! 

Back in the region near “Main Topsail” and “Salmon Point,” the team attempted to abrade and sample the clay-bearing rocks at a few different targets. These rocks, however, are proving very breakable and difficult to sample and abrade. Perseverance has experienced challenging fine-grained rocks before, such as during the fan front campaign inside Jezero crater. In that scenario and this one, the Science and Engineering teams work together diligently to find the highest priority targets and find rocks that could withstand the abrasion and coring processes. In this case, the team has decided to return to the site of a previous abrasion, “Strong Island,” to sample the rock we have already abraded and analyzed. This abrasion showed the strong clay signature the team is looking to sample, and we will make another coring attempt this week. 

NASA’s Mars Perseverance rover acquired this image of the target “Gallants,” named by Make-A-Wish participant Joshua, located in the lower left quadrant of the image. Perseverance used its onboard Left Navigation Camera (Navcam), which is located high on the rover’s mast and aids in driving, to capture the image on July 1, 2025 (Sol 1551 or Martian day 1,551 of the Mars 2020 mission), at the local mean solar time of 13:10:08. NASA/JPL-Caltech

This past week, the Perseverance team hosted two very special visitors, Madeline and Joshua, and had the unique honor of fulfilling their wishes through the Make-A-Wish foundation. During their visits to JPL, Madeline and Joshua were named honorary Mars 2020 Operations Team Members. They visited the test rovers in the JPL Mars Yard, watched data arrive from the rover with the Perseverance operations team, and attended a rover planning meeting, collaborating with the science and engineering team members on campus. Madeline and Joshua will forever be connected to the Mars 2020 mission, as each selected the name of one of our planning targets. Madeline’s target, “Jigging Cove,” was a target for Mastcam-Z and SuperCam “all techniques” analysis, including LIBS, VISIR, and RMI. Joshua’s selection, “Gallants,” will be used for the next coring target. Carrying forward the resilience shown by Madeline and Joshua, Perseverance will attempt to sample this clay-rich bedrock before continuing the investigation along the Jezero crater rim.
