Our moon may have once been as hellish as Jupiter's super volcanic moon Io
- New research suggests that the moon's orbit could have turned it into a molten monster resembling Jupiter's moon Io, with ongoing volcanic activity for a few million years.
- A massive protoplanet collision with Earth led to the formation of the moon, causing it to drift away and solidify over time.
- The moon's orbit was influenced by the sun's gravity, resulting in a gravitational mishmash that led to volcanic eruptions on the moon.
- Gravitational forces churned up the lunar interior, creating a magma layer that erupted to the surface, resetting the lunar surface about 4.35 billion years ago.
- Methods to determine the moon's age include analyzing moon rocks, lunar zircons, and dynamical models, suggesting an age of around 4.35 billion years.
- Volcanism on the moon would have lasted for tens of millions of years, with lava seeping through the surface rather than forming mountains.
- The moon's volcanism may have inhibited the formation of a magma ocean layer, with liquid material rising through the crust.
- During this period, the moon would have appeared larger in the Earth's sky, with glowing lava flows visible.
- The Io-like volcanic phase on the moon lasted for a brief but energetic period of a few tens of millions of years.
- The moon's volcanic past sheds light on its tumultuous history and the processes that shaped its surface over billions of years.

'Yet another miracle save': NASA engineers complete nail-biting maneuver to resurrect Voyager 1's long-dead thrusters
- NASA engineers have successfully revived Voyager 1's long-dead thrusters, providing a crucial backup just before a planned communications blackout.
- This fix has extended the spacecraft's operation until contact with Earth is reestablished next year.
- Launched in 1977, Voyager 1 is over 15 billion miles away from Earth and requires 23 hours for a radio signal to reach our planet.
- The backup thrusters on Voyager 1 had been clogging up with propellant residue, posing a challenge for the spacecraft's orientation.
- Despite facing issues since 2004, Voyager 1 continued its journey into interstellar space, providing valuable data about conditions outside the heliosphere.
- NASA engineers had to resort to remote fixes due to the craft's high speed and remoteness in interstellar space.
- A critical antenna upgrade and looming backup thruster issues prompted NASA engineers to take immediate action to fix the heaters remotely.
- The engineers successfully fixed the thruster heaters, ensuring Voyager's continued operation beyond the potential antenna blackout.
- The team's efforts were praised as another 'miracle save for Voyager,' prolonging the spacecraft's mission despite inevitable instrument shutdowns.
- As Voyager 1 and Voyager 2 continue their journeys, the spacecraft face diminishing power reserves and impending shutdowns.

Universe’s end – sooner rather than later
- Dutch researchers propose universe could decay in roughly 10^78 years, compared to 10^100 years previously believed, based on reinterpretation of Hawking radiation.
- According to the new theory, all massive objects with a gravitational field, including white dwarfs and neutron stars, would vanish sooner than expected, with white dwarfs lasting only 10^78 years.
- No matter the density or mass, all objects, including the Moon or human body, will eventually evaporate via this universal radiation concept in about 10^90 years.
- Implications of this research go beyond changing the cosmic timeline, potentially bridging the gap between quantum mechanics and general relativity, hinting at spacetime being fundamentally quantum and providing a new path towards a theory of quantum gravity.

New study finds ancient Mars likely had rainfall, snow and flowing rivers
- Recent research suggests that ancient Mars had a climate capable of supporting rainfall, snow, and flowing rivers billions of years ago.
- Valley networks on Mars hint at a planet with an active climate and possibly precipitation, contrary to previous cold and icy climate models.
- The study used computer simulations to compare theories of ice melting versus precipitation in forming Martian valleys.
- Evidence points towards precipitation being the more likely scenario for the formation of valleys on Mars.
- The Noachian epoch, when these valleys formed, dates back 4.1 to 3.7 billion years, during a time when Mars received less sunlight.
- The study suggests that deep valleys on Mars required prolonged water flow, indicating a hydrologic cycle similar to Earth's.
- Simulations showed that valleys at various elevations on Mars matched more closely with the precipitation model than the ice-melt model.
- The findings imply that ancient Mars might have had habitable conditions and stable environments for potential microbial life.
- Studying Mars could provide insights into early Earth's conditions and the origins of life on our own planet.
- Future missions like NASA's Perseverance rover will further contribute to understanding Mars' past climate and potential for supporting life.
