Selfie on Mars? Here's how NASA caught a new glimpse of the Martian surface
A Martian selfie is giving Earthbound astronomers a look at environmental details on the red planet's surface.
But the selfie was not taken by an extraterrestrial. Rather, it was a manmade explorer.
On May 10, NASA's Perseverance Mars rover used its 1,500th sol, or Martian day, to take a selfie from the edge of the Jezero Crater called 'Witch Hazel Hill,' according to NASA on Wednesday.
The selfie came together using a compilation of 59 individual pictures showing the whole rover and the Martian surface, NASA stated.
'To get that selfie look, each WATSON [Wide Angle Topographic Sensor for Operations and eNgineering] image has to have its own unique field of view,' Megan Wu, a Perseverance imaging scientist from Malin Space Science Systems in San Diego, said in NASA's statement. 'That means we had to make 62 precision movements of the robotic arm. The whole process takes about an hour, but it's worth it.'
Unique to the complete image is a swirling natural phenomenon seen on Earth. To the left of the center of the image is a dust devil, 'located 3 miles to the north in Neretva Vallis,' Justin Maki, Perseverance imaging lead at NASA's Jet Propulsion Laboratory in Southern California, said in NASA's statement.
'Having the dust devil in the background makes it a classic,' Wu said. 'This is a great shot.'
Located on a gray spot just below the rover is the 'Bell Island' borehole, in which the rover collected a sample of Mars' soil, astronomers said.
The selfie also gives NASA a chance to see what the Perseverance rover looks like over four years since it landed on the red planet. Though covered in dust, an American flag can still be seen on the rover's chassis. At the time the selfie was taken, Perseverance analyzed 37 rocks and boulders, collected 26 rock cores and has used its six wheels to drive more than 22 miles since it landed.

Long-Dead NASA Satellite Suddenly Lets Out Epic Blast of Energy
NASA's experimental Relay 2 satellite had been dead in the sky since 1967 — until last summer, when it emitted a super-short and very powerful burst of energy out of nowhere. In an interview with New Scientist, one of the researchers from Australia's Curtin University who discovered the strange pulse coming off the dead communications satellite described his shock at finding the nearby source of that nanosecond-long energy blast. Curtin astronomer Clancy James and his team had been using the Australian Square Kilometer Array Pathfinder (ASKAP) radio telescope array when they detected something so "loud" that it briefly outshone everything else in the night sky. Even stranger, it turned out, the signal was coming from so close to Earth that ASKAP's radio telescopes couldn't all focus on it at once. "We got all excited, thinking maybe we'd discovered a new pulsar or some other object," James told New Scientist. "This was an incredibly powerful radio pulse that vastly outshone everything else in the sky for a very short amount of time." As explained in a new paper that's now awaiting peer review, the Curtin researchers eventually traced the source of the pulse to NASA's derelict Relay 2 — but that discovery raised more questions than answers. Because Relay 2 had been dead for nearly 60 years, the Curtin team thinks that something either collided with the defunct communications craft that made it produce such a wild racket, or that electricity had been building up within it for so long that it resulted in a huge type of energy burst known as an "electrostatic discharge." As astrophysicist Karen Aplin of the UK's University of Bristol told New Scientist, all the space junk crowding Earth's orbit makes it nearly impossible to determine if either of those explanations, or any other, is correct. (That problematic crowding of Earth's orbit, it's worth pointing out, was not a pressing issue during Relay 2's short life in the mid-1960s.) "In a world where there is a lot of space debris and there are more small, low-cost satellites with limited protection from electrostatic discharges, this radio detection may ultimately offer a new technique to evaluate electrostatic discharges in space" explained Aplin, who was not involved in the research.

NASA's New Data Has Scientists Sounding the Alarm on Climate Extremes
The latest satellite data from NASA is painting a troubling picture of Earth's climate, and it's coming into focus faster than expected. According to new research from NASA's Goddard Space Flight Center, extreme weather events like floods and droughts are not only becoming more common, but also more intense, longer-lasting, and more destructive. The Guardian reported that data from the past five years show these events doubling in intensity compared to averages between 2003 and 2020. Even researchers behind the study admit they didn't anticipate such a dramatic spike. "We were surprised to find the actual population living in rural areas is much higher than the global data indicates," said lead researcher Dr. Bailing Li, who helped compile the figures using NASA's Grace satellite and dam relocation data across 35 countries. The result: a grim confirmation that climate change is fueling a shift in the planet's water systems, and the consequences are just data, which has not yet been peer-reviewed, reveals that global extremes now show a stronger correlation with rising temperatures than with other climate drivers like El Niño. Events are lasting longer, affecting wider areas, and shifting with less predictability—creating what scientists call "hydroclimatic whiplash," sudden transitions from drought to flood or vice versa. What's most worrying isn't just the scale of the change, but how unprepared most of the world remains. Experts say the current infrastructure, especially in water management, was built for a different era—one with a more stable climate. Christopher Gasson of Global Water Intelligence warned that most water systems are facing extremes from both ends—too much water or too little—and that investment must scale quickly to keep up. Meteorologists and climate experts across the globe echoed the concern. Richard Betts of the UK's Met Office called the data "a stark reminder" that what was once theoretical is now reality. He stressed that most societies have built their systems around past weather patterns, leaving them vulnerable to extremes that now fall outside the historical norm. With the World Meteorological Organization predicting an 80% chance that one of the next five years will be Earth's hottest ever, the window for adapting is narrowing. NASA's findings serve as a warning: the planet is heating up, and the consequences are already surging across every New Data Has Scientists Sounding the Alarm on Climate Extremes first appeared on Men's Journal on Jun 22, 2025

New marine life database touted as tool for ocean research
Biologists have launched a database of marine animals' body sizes that they say could help preserve biodiversity in Earth's oceans. Why bother measuring animals' body size? In an article in Global Ecology and Biogeography, researchers write that body size affects animals in a multitude of ways, from their behavior and favorite foods to their physiology and habitat choices.
