If there’s alien life nearby, where are we most likely to find it?
From nearby planets like Venus and Mars, to distant moons like Europa and Titan, these are worlds where we’re most likely to find alien life.

The homes we inhabit in the 2020s could serve as a personal headquarters for building the good society. How can a house help create a more positive future? Here are four ways the home of the future might support meaningful personal commitment to the greater good.
During the pandemic lockdown period, a new wave of civic engagement has taken hold. A trend called Advocate From Home (AFH) takes the form of digital organizing (e-mail, text banking, content production) for political, ecological, social and economic justice, often using work-from-home tools.
Households are embracing renewables in terms of solar energy and decentralized systems with independent home batteries. There are revolutions happening in the world of clean kinetic energy that could transform our spaces by allowing objects to collect and then transmit power. Future homes may be self-sustaining in terms of power and energy needs.
One way people express environmentalist values at home is through a love of nature. Outdoors, there are green options for the visionary homeowner, such as garden plots, low-intensive watering solutions, use of native plants and compost bins. Inside the home, people are gravitating to hydroponically grown vegetables and herbs. Indoor plants of all kinds are at the height of interior design trends and architecture is looking to biomimicry for sustainable ideas. Pets outnumber children in US homes.
Landfill, aka garbage dumps or tips, can, under the right conditions, be converted into solar farms once they’re capped.
Sky surveys are invaluable for exploring the universe, allowing celestial objects to be catalogued and analyzed without the need for lengthy observations. But in providing a general map or image of a region of the sky, they are also one of the largest data generators in science, currently imaging tens of millions to billions of galaxies over the lifetime of an individual survey. In the near future, for example, the Vera C. Rubin Observatory in Chile will produce 20 TB of data per night, generate about 10 million alerts daily, and end with a final data set of 60 PB in size.
As a result, sky surveys have become increasingly labor-intensive when it comes to sifting through the gathered datasets to find the most relevant information or new discovery. In recent years machine learning has added a welcome twist to the process, primarily in the form of supervised and unsupervised algorithms used to train the computer models that mine the data. But these approaches present their own challenges; for example, supervised learning requires image labels that must be manually assigned, a task that is not only time-consuming but restrictive in scope; at present, only about 1% of all known galaxies have been assigned such labels.

DARPA has selected four industry and university research teams for the Invisible Headlights program, which seeks to determine if it’s possible for autonomous vehicles to navigate in complete darkness using only passive sensors.
Solar and wind power have proven themselves to be cost competitive, but energy storage is key. What if I told you that molten metal might make a better battery? Lower cost, simpler assembly, zero maintenance, and a longer lifetime than lithium-ion. Let’s take a closer look at liquid metal battery technology.
