With 5,000 tiny robots in a mountaintop telescope, researchers can look 11 billion years into the past. The light from far-flung objects in space is just now reaching the Dark Energy Spectroscopic Instrument (DESI), enabling us to map our cosmos as it was in its youth and trace its growth to what we see today.
Did Mars once contain life, or even the building block for life? This is what NASA’s Perseverance (Percy) rover has been trying to determine ever since it landed in Jezero Crater, which has shown an overwhelming amount of evidence to have once been site to a massive lakebed. Now, NASA recently announced that Percy has collected its 24th rock sample on March 11th, nicknamed “Comet Geyser”, with this sample being unlike the first 23 in that evidence suggests it was submerged in standing water for an indeterminant amount of time when Mars had liquid water billions of years ago.

“To put it simply, this is the kind of rock we had hoped to find when we decided to investigate Jezero Crater,” said Dr. Ken Farley, who is a project scientist for Perseverance and a professor of geochemistry at the California Institute of Technology. “Nearly all the minerals in the rock we just sampled were made in water; on Earth, water-deposited minerals are often good at trapping and preserving ancient organic material and biosignatures. The rock can even tell us about Mars climate conditions that were present when it was formed.”
The Messier 82 Galaxy (commonly known as M82) is a starburst galaxy located approximately 12 million light-years from Earth, with starburst meaning it is experiencing an unusually high rate of star formation, with approximately 10 times the number of stars being formed compared to our own Milky Way Galaxy. While M82 has a long history of being studied, specifically by NASA’s Hubble Space Telescope, a recent study published in The Astrophysical Journal uses data from NASA’s James Webb Space Telescope (JWST) to conduct more in-depth observations of M82 and its starburst characteristics.

“M82 has garnered a variety of observations over the years because it can be considered as the prototypical starburst galaxy,” said Dr. Alberto Bolatto, who is a professor in the Department of Astronomy at the University of Maryland and lead author of the study. “Both NASA’s Spitzer and Hubble space telescopes have observed this target. With Webb’s size and resolution, we can look at this star-forming galaxy and see all of this beautiful, new detail.”
NASA has given three space companies the chance to design the next-generation moon buggy — but only one design will go to space. Intuitive Machines, Lunar Outpost, and Venturi Astrolab are developing rugged vehicles intended for astronauts to drive around on the lunar surface, from which NASA may choose as early as next year.
The three teams will now enter into a 12-month “feasibility phase” that will culminate in a preliminary design review. At that point, there will be a subsequent competitive request for proposals, where the trio of companies will compete for a demonstration task order, NASA officials explained during a press conference on Wednesday.
At that point, a final awardee will be selected. The chosen company will be responsible not only for designing the lunar terrain vehicle (LTV) but also for launching and landing it on the moon prior to the Artemis V mission, which is currently slated for no earlier than 2029.

Chinese e-commerce giant Alibaba Group Holding is partnering with a domestic rocket developer, with the lofty goal of delivering parcels anywhere in the world within an hour.
The experiment, to be co-conducted by Alibaba’s Taobao marketplace and Beijing-based start-up Space Epoch, will take place “in the near future” using a reusable rocket that can land on the sea, according to a Sunday post by Space Epoch on its official WeChat account.
Alibaba, which owns the South China Morning Post, confirmed the information on Monday, saying that “many great endeavours seem like a joke at first”
Combining results of laboratory studies on the infra-red glow of carbon molecules in simulation software has led a team of researchers to a new discovery about the creation of spherical carbon ‘cages’ called fullerenes.
Given these molecules could have protectively carried complex compounds through the harshness of interstellar space, the findings could have implications for how life arose on Earth, and beyond.
Following the confirmed detection of fullerenes surrounding the dusty surrounds of dying stars called planetary nebulas in recent decades, researchers have pondered the process that led to their creation.
It remains a fascinating system for astronomers because the protostar and its protoplanetary disk are estimated to be no older than 5.5 million years — a cosmic infant compared to our 4.5-billion-year-old solar system.
“PDS 70 is special, as it is the only protoplanetary disk so far where all astronomers agree that we have found forming planets caught in the act,” Christiaens said. “Detailed study of this system has thus allowed us to learn a lot about planet formation.”
The researcher said that little is known about the properties of the potential third planet around PDS 70 thus far. The planet — which, if confirmed, would be designated PDS 70D — appears to be shrouded in a vast amount of dust, and it orbits its infant star at around 13 times the distance between Earth and the sun.
The rover will spend months exploring the Gediz Vallis channel, which could contain clues to the history of liquid water on Mars.
Galaxies start life with their stars rotating in an orderly pattern but in some the motion of stars is more random. Until now, scientists have been uncertain about what causes this—possibly the surrounding environment or the mass of the galaxy itself.
