NASA released a significant update from the Perseverance Mars rover on Wednesday, focusing on a particularly juicy tidbit for those watching from home: A small rock sample called Sapphire Canyon showed signs of potential biosignatures, or ancient alien life that may have once grown on Mars.

That’s possible because of the unique location where Perseverance located the sample in July 2024. It came from a rock named Cheyava Falls. This particular rock is in Jezero Crater, home to an ancient dry riverbed. In other words, water once flowed abundantly in this spot, one of the most essential requirements for life as we know it.

A representative for NASA did not immediately respond to a request for comment. 

While exploring, Perseverance’s cameras picked up colorful, leopard-like spots that eventually led to the Sapphire Canyon discovery.

«This finding is the direct result of NASA’s effort to strategically plan, develop, and execute a mission able to deliver exactly this type of science — the identification of a potential biosignature on Mars,» said Nicky Fox, associate administrator, Science Mission Directorate at NASA headquarters in Washington.

Life on Mars?

So, does this finally confirm that life once existed on Mars? It’s a very good start, and the most significant lead NASA has found so far. 

The data collected by Perseverance using its onboard instruments (X-ray lithochemistry and NASA’s SHERLOC scanner) was peer-reviewed and appears promising, but it doesn’t absolutely confirm life. More tests and input are needed for that, and the samples could have been generated from a natural chemical process without the presence of life. But scientists are excited about these signs and eager to learn more.

What kind of Mars life are we talking about? It’s not the sort that comes in peace, or goes much of anywhere. The possible biosignatures indicate small, microbial life. Sapphire Canyon showed signs of vivianite and greigite. Vivianite, in particular, is found on Earth’s peat bogs and swamps, while greigite is a byproduct some earth microbes leave behind. Think of this finding like a potential algae or swamp scum.

NASA is working on analyzing the data, running more tests and sharing the results with other scientists around the world to see what more they can learn. There’s a lot to rule out, from accidental sample contamination to the likelihood of nonorganic origins. That’s tough to do from millions of miles away, but NASA is on the case.

Lossless audio, a format that Spotify says has been much-requested by subscribers over the years, is finally arriving on the streaming service.

In a post, the company says that 24-bit/44.1kHz FLAC audio will now be an option for premium subscribers in select markets «across nearly every song available in Spotify.»

Subscribers will have the option to adjust music quality as low, normal, high, very high and now lossless, with the option to see how much data each tier requires.
While audio formats such as MP3 or AAC use varying degrees of compression to reduce file sizes — which means you don’t get the full depth and range of the music — lossless formats including FLAC and Apple’s ALAC preserve the original data from a song without any quality loss.

In addition to working in Spotify’s apps, the company says, lossless audio will be available on some Spotify Connect devices from Sony, Bose, Samsung, Sennheiser and other manufacturers. It plans to add support for Sonos and Amazon audio devices next month, according to the post.

The lossless feature has been a missing component on the service, which launched in 2008 and became available in the US in 2011. Some of its audio-streaming competitors added lossless before Spotify.

«Spotify has promised a lossless music tier for many years, originally dubbed Supremium, and it is one of the last of its competitors to add uncompressed tunes,» said Ty Pendlebury, TV and home video editor at CNET. «Both Apple and Amazon added complimentary lossless and hi-res files back in 2021, while YouTube Music is one of the only holdouts by only offering compressed music.»

Spotify says lossless is eventually rolling out to 50 different markets.

How to enable lossless audio on Spotify

Once you receive a notification from Spotify that lossless is available, you can use the Spotify app to enable the feature.

To do this, tap on your profile image, go to Settings & Privacy, then Media Quality and select where to enable the format: over Wi-Fi, over cellular or in downloads.

The company says you need to enable the feature manually for each device you use.
