The Perseverance Rover has found evidence of organic compounds in the Jezero Crater on Mars. Although this isn’t the smoking gun proving once and for all that Mars once hosted life — these compounds could have also developed in nonbiological ways — the results hint at surprisingly complex organic conditions for the “key building blocks for life” on Earth’s neighbor. The study was published in Nature.

The Perseverance Rover, the first to explore the Jezero Crater, has been investigating the area since February 2021. Researchers believe the basin once housed an ancient lake, including a delta from a river that once flowed into it. It’s one of the most likely regions to reveal leftover signs of life on Mars.

Organic molecules like those observed in the Jezero Crater contain carbon and often hydrogen atoms. They’re the core components of life as we know it on Earth, although they can also develop abiologically. “They are an exciting clue for astrobiologists since they are often thought of as building blocks of life,” paper co-author Joseph Razzell Hollis, a postdoctoral fellow at London’s Natural History Museum, said toNewsweek. “Importantly, they can be created by processes not related to life as we know it, and so organic molecules are not evidence of life on their own without sufficient extra evidence that cannot be explained by nonbiological — or abiotic — processes.”

The rover observed the compounds using an instrument — the Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals (SHERLOC) — that maps organic molecules and minerals on rock surfaces. Significantly, it found organic materials in all ten targets it observed on the crater floor. “Our results support observations by previous robotic missions to Mars that the Red Planet was once rich in organic material, compounds made primarily of carbon and hydrogen, and that some of that organic material can still be detected billions of years later,” co-author Joseph Razzell Hollis, a London-based astrobiologist, toldGizmodo. “Each detection, each observation, gives us a little bit more information that brings us closer to understanding the history of Mars and whether it could have supported life in the past.”

Now that the researchers have observed the molecules, they’ll need a better look at them in Earthbound labs to draw further conclusions about their origins. “If these samples are returned to terrestrial laboratories, a more diverse suite of tools can be used to study the samples, including at higher spatial resolution and with much greater specificity and sensitivity,” the authors wrote. They’ll have to wait for the Mars Sample Return (MSR) mission, which isn’t expected to launch from Earth until at least the late 2020s. Still, the trip should be worth the wait. “So far, the only Martian rocks we’ve ever been able to study on Earth have been meteorites. Getting our hands on intact Mars rocks, carefully stored and protected from contamination, will be invaluable to planetary science,” Razzell Hollis told Newsweek.

Tons of speakers are on sale for Prime Day this year — though not all of those speakers are winners. Luckily, many of the soundbars, smart speakers and portable options we’ve tested in our reviews and recommend in our guides are seeing notable discounts today. Take advantage of a discounted Bluetooth speaker so you can bring your music with you this summer, or snag a deal on a soundbar and finally clearly hear all that dialogue on your TV. Naturally, Amazon’s Echo speakers are part of the sale too, so you can get Alexa’s help for less as well. Here are the best Prime Day speaker deals we could find.

Amazon Echo (4th gen)

Compared to the similarly priced Nest Audio or HomePod mini smart speakers, Amazon’s Echo is louder and pumps out better audio. We named it the best speaker under $100 in our smart speaker guide and right now it’s down to a low of $55 for Prime members, which is about $5 more than it sold for on Black Friday, which was the all-time low. This is the latest generation, which came out in 2020, after a redesign put music quality front and center. It also nicely handles all Alexa duties like music streaming control and launching smart home routines.

Amazon Echo Dot

The smaller version is actually Amazon’s best-selling Echo device. And right now the Echo Dot is down to $23 for Prime Day, which is a 54 percent discount over its usual $50 price tag and the lowest its gone since its release last year. Engadget named it the best smart speaker under $50 in our buyer’s guide because it produces louder and clearer sound than you’d expect from such a small device. It also delivers Alexa’s help, like answering questions, setting timers and controlling your smart home just by asking.

Echo Studio

The Echo Studio is Amazon’s biggest smart speaker and is currently on sale for $155, which is 23 percent off its regular price of $200 and matches its all-time low. The focus here is the quality of the audio and we gave it an 88 in our review, impressed with the hi-res sound. It’s not a small speaker at nearly eight pounds and over eight inches tall, but all that space manages to pack three two-inch midrange speakers, a single one-inch tweeter and a 5.25-inch downward-facing woofer.

Bose SoundLink Flex

Bose’s SoundLink Flex is one of our recommended Bluetooth speakers under $200. Usually $150, it’s down to $129 for Prime members, which is a $40 discount that matches the lowest price. It gives bright, dynamic finesse to music and delivers a significant amount of bass for its size. It’s about the size of a clutch bag and even has a small loop strap to further the comparison. And of course it’s IP67 rated so it can handle the elements.

Ultimate Ears Wonderboom 3

The Wonderboom 3 from Ultimate Ears is currently 30 percent off for Prime Day, dropping it down to $70 instead of the usual $100. That’s the lowest price we’ve seen in a while, matching the all-time low it hit just before Black Friday last year. In our tests, the Wonderboom 3 delivered the biggest sound of any speakers in its size range, plus it has a cute design with a strap and comes in bright blue, hot pink or a more sedate gray (note that the black colorway isn’t discounted).

Anker Soundcore Motion +

Anker’s Soundcore Motion + is normally $100 but is discounted to $75 for Prime members as a Lightning Deal. In our guide, we said it produces good sound for the price, which is even more true now. It’s a little heavier than you’d expect, and the soft-touch exterior shows fingerprints, but if those aren’t deal-breakers for you, you’ll enjoy bright and bassy output, a connected app with EQ customization and IPX7 water resistance.

Anker Soundcore 2

With over 100k positive ratings, Anker’s tiny but mighty Soundcore 2 is a great buy at its usual $40, but Prime Day savings bring it down to just $28 for Prime members. It has a IPX7 rating so it can handle an accidental dunk in water and the battery will deliver a claimed 24 hours of play time. Two Soundcore 2s can pair up for stereo sound, so if the price tempts you to get a set, you may as well go for it.

JBL Charge 5

JBL’s Charge 5 is usually $180 but is down to $120 for Prime members. It also made Engadgets speaker guide, and has a separate tweeter, and dual bass radiators for bigger sound and of course can handle a dunk in water. It’s got a long, 20-hour battery life and can even share some of that juice with your phone via the USB-C port.

JBL Boombox 2

JBL’s Boombox 2 is $250 for Prime Day, which is $200 off the list price. We recommend the third generation of JBL’s Boombox speaker in our guide because it’s loud and comes in a take-anywhere package. This previous model offers 24 hours of playback, has a waterproof design and can recharge your phone. At 13 pounds, it’s big but still portable.

Sony SRS-XP700

Sony’s party-sized SRS-XP700 Bluetooth speaker is down to $398 after a $150 discount for Prime Day. It pumps out loud, thumping beats, stands over two feet tall and emits lighting effects that sync with what’s playing. It weighs 37 pounds, so the grab bars on the top and bottom make a lot of sense. It can go for 25 hours on a charge and offers a bit of water-resistance to accidental splashes, but its size and build make it less rough and tumble than other portable Bluetooth speakers.

Sony SRS-XB13 EXTRA BASS

The SRS-XB13 speaker stands a little over four inches tall and is going for just $35 for Prime Day, which is 43 percent off its list price. This is the previous model, which was replaced this year by the SRS-XB100. But if you don’t have to live on the cutting edge, you’ll get a portable unit that’s rated IP67 for water and dust resistance and uses Sony’s Sound Diffusion Processor which is designed to deliver “rich dynamic sound.” Plus you can pair two for stereo effects.

Samsung HW-Q700B

Samsung’s HW-Q700B soundbar is currently $398 for Prime members after a steep 47 percent discount off its $698 MSRP. It’s the runner-up midrange soundbar in Engadget’s guide and supports Dolby Atmos and Q-Symphony, which allows you to play sound from both the soundbar and your late model Samsung TV. Other Samsung tech like SpaceFit and Adaptive Sound help automatically calibrate the speaker to sound better in your space.

Vizio V21t-J8

The Vizio V21t-J8 carries a list price of $160 but is presently $140 for Prime Day, which isn’t an all time low and just $20 off but we think this is the best budget soundbar you can buy, even when it’s full price. It doesn’t take up a lot of space and supports Bluetooth, HDMI ARC/eARC, 3.5mm and optical connections (but not WiFi). It also employs DTS Virtual:X, which promises more three-dimensional sound without requiring a bunch of extra speakers.
