Alien life? Maybe not, but NASA says there’s ‘surprising activity’ on Europa

NASA will hold a press conference Monday on what is being billed as “surprising evidence of activity” — and the possible discovery of a subsurface ocean — on Europa, one of Jupiter’s moons. While details are scant, a team of researchers is expected to unveil a set of images taken by the Hubble Space Telescope showing this activity.

While there has been speculation that this might be an announcement of the discovery of alien life, it likely is not. The presence of a subsurface ocean would definitely move Europa to the top of the list of potential candidates for the presence of such life, however.

Astronomers have long speculated that if there’s any chance of life in our solar system, it’s likely to be found on one of Jupiter’s moons. Europa’s icy crust has long led scientists to suspect a liquid ocean underneath, but Saturn moon Titan — the only moon known to have a dense atmosphere — is certainly another candidate.

“The cycling of oxygen and hydrogen in Europa’s ocean will be a major driver for Europa’s ocean chemistry and any life there, just as it is on Earth,” NASA planetary scientist Steve Vance said in May. Vance and his team had already demonstrated that any potential ocean would have the chemical balance necessary for life.

While Europa is some 500 million miles from the sun, scientists think the key to life there is the moon’s likely warm mantle. The combination of that warm center and the super thick ice crust at the top, which keeps out the coldness of space, could allow any liquid water between to stay at a life-supporting temperature.

What we’re likely to hear on Monday is some type of evidence of movement underneath this crust, which would confirm speculation of liquid water. The next step would be a closer observation, which NASA does plan to do.

A probe would be launched to Europa in the mid 2020s under current plans, and fly by the surface about 45 times while taking high-resolution pictures. There are no plans to take the probe to the surface, but we should at least get some clearer pictures of the interior of Europa using a variety of methods.

Toyota shifts gears: 15 New EVs and a million cars by 2027

After years of cautiously navigating the electric vehicle (EV) market, Toyota is finally ramping up its commitment to fully electric vehicles.
The Japanese automaker, which has long relied on hybrids, is now planning to develop about 15 fully electric models by 2027, up from five currently. These models will include vehicles under the Toyota and Lexus brands, with production expected to reach 1 million units annually by that year, according to a report from Nikkei.
This strategy marks a significant shift for Toyota, which has thus far remained conservative in its approach to electric cars. The company sold just 140,000 EVs globally in 2024—representing less than 2% of its total global sales. Despite this, Toyota is aiming for a much larger presence in the EV market, targeting approximately 35% of its global production to be electric by the end of the decade.
The Nikkei report suggests the company plans to diversify its production footprint beyond Japan and China and expanding into the U.S., Thailand, and Argentina. This would help mitigate the impact of President Donald Trump’s 25% tariffs on all car imports, as well as reduce delivery times. Toyota is also building a battery plant in North Carolina.
For now, Toyota has only two fully electric vehicles on the U.S. market: The bZ4X  and the Lexus RZ models. The Japanese automaker is expected to introduce new models like the bZ5X and a potential electric version of the popular Tacoma pickup.
Separately, Toyota and Honda, along with South Korea’s Hyundai, all announced on April 4 that they would not be raising prices, at least over the next couple of months, following the imposition of U.S. tariffs. According to a separate Nikkei report, Toyota’s North American division has told its suppliers that it will absorb the extra costs of parts imported from Mexico and Canada. Another 25% for automotive parts imported to the U.S. is slated to come into effect on May 3.

Tesla, Warner Bros. dodge some claims in ‘Blade Runner 2049’ lawsuit, copyright battle continues
Tesla Cybercab at night

Tesla and Warner Bros. scored a partial legal victory as a federal judge dismissed several claims in a lawsuit filed by Alcon Entertainment, a production company behind the 2017 sci-fi movie Blade Runner 2049, Reuters reports.
The lawsuit accused the two companies of using imagery from the film to promote Tesla’s autonomous Cybercab vehicle at an event hosted by Tesla CEO Elon Musk at Warner Bros. Discovery (WBD) Studios in Hollywood in October of last year.
U.S. District Judge George Wu indicated he was inclined to dismiss Alcon’s allegations that Tesla and Warner Bros. violated trademark law, according to Reuters. Specifically, the judge said Musk only referenced the original Blade Runner movie at the event, and noted that Tesla and Alcon are not competitors.
"Tesla and Musk are looking to sell cars," Reuters quoted Wu as saying. "Plaintiff is plainly not in that line of business."
Wu also dismissed most of Alcon's claims against Warner Bros., the distributor of the Blade Runner franchise.
However, the judge allowed Alcon to continue its copyright infringement claims against Tesla for its alleged use of AI-generated images mimicking scenes from Blade Runner 2049 without permission.
Alcan says that just hours before the Cybercab event, it had turned down a request from Tesla and WBD to use “an icononic still image” from the movie.
In the lawsuit, Alcon explained its decision by saying that “any prudent brand considering any Tesla partnership has to take Musk’s massively amplified, highly politicized, capricious and arbitrary behavior, which sometimes veers into hate speech, into account.”
Alcon further said it did not want Blade Runner 2049 “to be affiliated with Musk, Tesla, or any Musk company, for all of these reasons.”
But according to Alcon, Tesla went ahead with feeding images from Blade Runner 2049 into an AI image generator to yield a still image that appeared on screen for 10 seconds during the Cybercab event. With the image featured in the background, Musk directly referenced Blade Runner.
Alcon also said that Musk’s reference to Blade Runner 2049 was not a coincidence as the movie features a “strikingly designed, artificially intelligent, fully autonomous car.”

Audi halts vehicle deliveries to the U.S. as it mulls impact of tariffs
2021 Audi Q5

If you’d been thinking of buying an Audi, now might be the time.  The German brand, owned by the Volkswagen Group, has announced it would halt shipments to the U.S. in the wake of President Donald Trump’s 25% tariffs on all imported vehicles.
Audi is currently holding cars that arrived after the tariffs took effect, on April 3, in U.S. ports. But it still has around 37,000 vehicles in its U.S. inventory, which should be able to meet demand for about two months, according to Reuters.
Automakers on average hold enough cars to meet U.S. demand for about three months, according to Cox Automotive.
Audi should be particularly affected by the tariffs: The Q5, its best-selling model in the U.S., is produced in Mexico, while other models, such as the A3, A4, and A6 are produced in Germany.
Holding shipments is obviously a temporary measure to buy time for Audi and parent company Volkswagen. If tariffs stay in place, vehicle prices would likely have to go up accordingly, unless some production is shifted to the U.S. Volkswagen already has a plant in Chattanooga, Tennessee, and is planning a new plant in South Carolina. That latter plant, however, isn’t expected to be operational until 2027 and is currently dedicated to building electric vehicles for VW’s Scout Motors brand.
Other global automakers have also taken drastic measures in response to Trump’s tariffs. Jaguar Land Rover on April 5 said it is pausing shipments of its its UK-made cars to the United States this month. The British sports-luxury vehicle maker noted that the U.S. market accounts for nearly a quarter of its global sales, led by the likes of Range Rover Sports, Defenders, and Jaguar F-PACE.
And on April 3, Nissan, the biggest Japanese vehicle exporter to the United States, announced it will stop taking new U.S. orders for two Mexican-built Infiniti SUVs, the QX50 and QX55.
