The robots contain miniaturized sensors which are deployed as they traverse a cave or other subsurface environment.

Life on Mars is closer than you think. And researchers at the University of Arizona College of Engineering are already scouting real estate and house hunting. Their helpers? A flock of robots that can explore the subsurface environments on other worlds.

“Lava tubes and caves would make perfect habitats for astronauts because you don’t have to build a structure; you are shielded from harmful cosmic radiation, so all you need to do is make it pretty and cozy,” said Wolfgang Fink, an associate professor of electrical and computer engineering at UArizona.

New simulations paint a picture of our solar system resembling an ornate clock. “Throw more gears into the mix and it all breaks.”

A new experiment shed new light on the role Jupiter has played in the evolution of life on Earth. In a series of simulations, scientists showed that an Earth-like planet orbiting between Mars and Jupiter would be able to alter Earth’s orbit and push it out of the solar system.

Such an event would extricate Earth from its life support system, the Sun, and would therefore wipe out all life on our planet.

To us everything seems normal. Our planet, blue and bursting with life, sits in the middle of the “habitable zone” around the Sun, with burning hot Venus inwards and lifeless Mars beyond. Giant gas planets exist way farther out. That’s as how it should be, right?

An updated look at how we are preparing to search the solar system in SETI to see whether anyone has ever stationed an alien probe in the star system including just what we might look for.

Group of academics say they have identified fossilised sponges, corals, worm eggs, algae and more on planet’s surface.

Is it a millipede? Is it a rock?

That is the question that is troubling some scientists who believe that life may already have been found on Mars, if you just look carefully enough.

“We Can Remember It for You Wholesale” is a short story by Philip K. Dick first published in The Magazine of Fantasy & Science Fiction in April 1966. It features a melding of reality, false memory, and real memory. The story has been the subject of two film adaptations, 1990’s Total Recall, with Arnold Schwarzenegger as the story’s protagonist; and 2012’s same-titled with Colin Farrell in a similar role.

In this episode of the Physics World Weekly podcast we meet three scientists who are trying to answer a question that humanity has long pondered: does intelligent life exist elsewhere in the universe?

Peter Ma and Leandro Rizk of the University of Toronto and Cherry Ng of the French National Centre for Scientific Research in Orleans are part of a team that has used machine learning to identify eight potential “technosignatures” in data from the Robert C Byrd Green Bank Telescope. The trio explain how they look for signs of intelligent life in radio-telescope data and how machine learning gives a helping hand.

Ng also talks about her research on how signals from pulsars could be used to detect gravitational waves.

The renowned physicist and science communicator, Brian Cox delves into the topic of alien life and in particular, the question about intelligent alien civilization.
With his trademark enthusiasm and engaging style, Brian Cox explores the possibility of extraterrestrial life and why we haven’t found any.

The video starts with a brief overview of what Brian Cox & astronomers call: “The Great Silence”. Cox then goes on to explain the Fermi Paradox and the Dark Forest Hypothesis, which suggest that intelligent life may be intentionally avoiding contact with other civilizations to avoid being destroyed.

Located in Austrailia, the CSIRO Parkes Radio Telescope picked up the strange signal stemming from Proxima Centauri.

CSIRO/A. Cherney.

On 29 April 2019, the Parkes Radio Telescope in New South Wales, Australia, picked up an unusual signal while searching for signs of intelligent life elsewhere in the universe. The telescope was observing Proxima Centauri, the nearest star to the sun and host to a number of exoplanets that are potentially habitable.
