“Houston, we have a new record.”

NASA’s Artemis I Orion capsule broke a new spaceflight record. The uncrewed Orion reached a distance from Earth of 249,666 miles (from 401,798 kilometers) on Saturday, November 26, at 10:17 am. ET, meaning it surpassed a record set by Apollo 13 in 1970 for the furthest distance traveled from Earth by a spacecraft designed to carry humans.

NASA’s Orion spacecraft broke a massive record.

The previous record was set by Apollo 13’s crewed Odyssey command module in 1970 when it traveled 248,655 miles (400,171 kilometers) from Earth. Orion crossed that threshold at 8:40 am. ET on November 26 before going on to extend the record.

SPEAKING at the University of Cambridge in 1980, Stephen Hawking considered the possibility of a theory of everything that would unite general relativity and quantum mechanics – our two leading descriptions of reality – into one neat, all-encompassing equation. We would need some help, he reckoned, from computers. Then he made a provocative prediction about these machines’ growing abilities. “The end might not be in sight for theoretical physics,” said Hawking. “But it might be in sight for theoretical physicists.”

Artificial intelligence has achieved much since then, yet physicists have been slow to use it to search for new and deeper laws of nature. It isn’t that they fear for their jobs. Indeed, Hawking may have had his tongue firmly in his cheek. Rather, it is that the deep-learning algorithms behind AIs spit out answers that amount to a “what” rather than a “why”, which makes them about as useful for a theorist as saying the answer to the question of life, the universe and everything is 42.

The search continues for signs of ancient alien life on the red planet.

NASA’s Perseverance mission on Mars has performed several world firsts, including the first controlled flight on another planet and the first extraction of oxygen from the Martian atmosphere.

New Mars findings point to ancient alien life.

The mission also confirmed once and for all last year that the Jezero Crater on Mars was once a massive lake. Now, a new study shows that organic molecules featured abundantly in these waters. The findings provide compelling evidence that life may have once existed on the red planet, as per a report by IFLScience.

Physicists have long struggled to explain why the universe started out with conditions suitable for life to evolve. Why do the physical laws and constants take the very specific values that allow stars, planets and ultimately life to develop? The expansive force of the universe, dark energy, for example, is much weaker than theory suggests it should be—allowing matter to clump together rather than being ripped apart.

A common answer is that we live in an infinite multiverse of universes, so we shouldn’t be surprised that at least one has turned out as ours. But another is that our universe is a computer simulation, with someone (perhaps an advanced alien species) fine-tuning the conditions.

The latter option is supported by a branch of science called information physics, which suggests that space-time and matter are not fundamental phenomena. Instead, the physical reality is fundamentally made up of bits of information, from which our experience of space-time emerges. By comparison, temperature “emerges” from the collective movement of atoms. No single atom fundamentally has temperature.

SpaceX sent one of its first-stage boosters skyward for the 11th time on Tuesday evening. However, unlike its 10 previous flights, this time it didn’t return.

The mission launched from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida at 9:57 p.m. ET, lighting up the night sky as the Falcon 9 rocket roared toward space.

Thirty-five minutes after leaving the launchpad, the Falcon 9’s second stage deployed a communications satellite to a geosynchronous transfer orbit for French satellite operator Eutelsat.

It’s frigid and strange and orbits its home planet backward.

But Enceladus isn’t the only location in our solar system with active geysers, as another small moon near the edge of the solar system shares similar characteristics, as well. This is Neptune’s largest moon, Triton, which has been visited only once by NASA’s Voyager 2 in 1989. But are Triton’s geysers the only characteristics that make it a good target for astrobiology and finding life beyond Earth?

“Triton may be an ‘ocean world’, a moon that has a solid ice crust over a liquid water subsurface ocean,” said Candice Hansen-Koharchek, a planetary scientist who was a Voyager Imaging Team Assistant Experiment Representative during the Voyager missions. “If that is the case, and if we are able someday to reach that ocean and find life, that would extend the habitable zone to the Kuiper Belt, not just the inner solar system. That has profound implications, both in our solar system and at exoplanets.”

Due to its geysers, which Voyager 2 identified as dark streaks, Triton is only the third known planetary body in the Solar System to be volcanically active, aside from Earth and Jupiter’s innermost Galilean moon, Io.

Microbial life may have resided within the first four kilometers of Mars’s porous crust.

Four billion years ago, the solar system was still young. Almost fully formed, its planets were starting to experience asteroid strikes a little less frequently. Our own planet could have become habitable as long as 3.9 billion years ago, but its primitive biosphere was much different than it is today. Life had not yet invented photosynthesis, which some 500 million years later would become its main source of energy. The primordial microbes — the common ancestors to all current life forms on Earth — in our planet’s oceans, therefore, had to survive on another source of energy. They consumed chemicals released from inside the planet through its hydrothermal systems and volcanoes, which built up as gas in the atmosphere.

Some of the oldest life forms in our biosphere were microorganisms known as “hydrogenotrophic methanogens” that particularly benefited from the atmospheric composition of the time. Feeding on the CO2 (carbon dioxide) and H2 (dihydrogen) that abounded in the atmosphere (with H2 representing between 0.01 and 0.1% of the atmospheric composition, compared to the current approximate of 0.00005%), they harnessed enough energy to colonize the surface of our planet’s oceans. we explore Mars, it is becoming clearer that similar environmental conditions were developing on its surface at the same time as those that enabled methanogens to flourish in the oceans back on Earth.
