The universe is dying much faster than scientists thought, new study suggests
- A new study suggests that the universe could be dying much quicker than previously thought, with a theoretical maximum lifespan estimated at around 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 years.
- This estimate is based on the decay of stellar remnants, with a new upper limit proposed by researchers, significantly shorter than the previous estimate of 101,100 years.
- The study underscores the inevitability of all things decaying, although there is still ample time left to achieve remarkable feats.
- Stars evolve into different remnants like white dwarfs and neutron stars, with the most massive ones ending in supernovae or black holes that can eventually evaporate.
- The researchers' theory suggests that all massive objects could decay, similar to black holes, through a process called gravitational pair production, leading to their eventual demise.
- The new findings highlight the potential lifespan of various stellar remnants and theorize that supermassive black holes could survive up to 1096 years.
- While the universe may not necessarily last as long as these estimates suggest, it is projected that galaxies will run out of material for star formation within that timeframe.
- In around 17 trillion years, the last stars in the universe are expected to have died, leaving only the stars in our own Galaxy visible to our human eyes.
- Our sun is predicted to expand and die in approximately 5 billion years, making our solar system uninhabitable well before the rest of the stars meet their end.
- The study on stellar remnant decay has been described as fascinating, showing that these remnants have a maximum possible lifetime before they decay through processes akin to Hawking radiation.

NASA Observes First Visible-light Auroras at Mars
- NASA's Perseverance Mars rover made history by detecting green auroras for the first time on Mars on March 15, 2024, during a solar storm.
- Unlike Earth, Mars lacks a global magnetic field leading to different types of auroras such as solar energetic particle (SEP) auroras.
- SEP auroras on Mars occur when energetic particles from the Sun interact with the Martian atmosphere, causing it to glow across the night sky.
- NASA coordinated with various teams to capture visible images and spectra of the SEP aurora from Mars' surface during the solar storm.
- The team strategically selected a strong Coronal Mass Ejection (CME) to trigger visible-light auroras on Mars for observation.
- Data from Perseverance and MAVEN's instruments confirmed the presence of solar energetic particles during the aurora observation.
- The successful detection of these auroras opens up new possibilities for future auroral research and potential observations by astronauts on Mars' surface.
- NASA's Perseverance and MAVEN missions played crucial roles in observing and understanding these phenomena, aiding in preparing for human exploration of Mars.
- This collaborative effort highlighted the importance of cross-mission coordination in capturing unique astral events like the green auroras on Mars.
- The observed 557.7 nm emission from solar energetic particles suggests that future Martian astronauts might witness similar auroras during their missions.

NASA’s Magellan Mission Reveals Possible Tectonic Activity on Venus
- New research based on NASA's Magellan mission data suggests that tectonic activity may be deforming Venus' surface, indicating ongoing tectonics on the planet.
- Coronae, vast quasi-circular features on Venus, are believed to be shaped by tectonic processes caused by molten material from the planet's mantle.
- A recent study published in Science Advances reveals new evidence of tectonic activity beneath Venus' coronae.
- Researchers studied coronae, which are thought to be locations where plumes of hot material rise from the mantle, influencing the planet's lithosphere.
- The study, led by Gael Cascioli, suggests that coronae on Venus could provide insights into Earth's past and present subsurface processes.
- NASA's upcoming VERITAS mission aims to provide high-resolution gravity data to further understand Venus' geological processes.
- Coronae formation on Venus involves various tectonic processes like subduction and lithospheric dripping, different from Earth's tectonic activities.
- The VERITAS mission will use advanced instruments to map Venus' surface, measure its gravitational field, and study its interior structure.
- Future data from VERITAS could revolutionize our understanding of Venus' geology, drawing parallels to early Earth's geological evolution.
- The Magellan mission, managed by NASA's Jet Propulsion Laboratory, made significant contributions to understanding Venus' geological features.

Lights on Mars! NASA rover photographs visible auroras on Red Planet for the first time
- NASA's Perseverance rover captured the first-ever photo of visible auroras on Mars, caused by a solar storm colliding with the planet's magnetic field.
- While not as visually stunning as Earth's auroras, Mars' auroras were emitted in visible wavelengths for the first time in the solar system.
- The faint green lights on Mars are believed to be the first auroras captured using visible light only, raising hopes for future human observation.
- Researchers positioned the rover to photograph the auroras after predicting that a solar storm would hit Mars.
- The detected green hues from the auroras were emitted by excited oxygen molecules in Mars' thin atmosphere.
- Humans may observe auroras on Mars in the future as solar particles increase and atmospheric dust decreases.
- The weak auroras were barely visible and appeared only after editing out the glare from Mars' moon, Phobos.
- Other planets in the solar system, like Venus, Jupiter, Saturn, Uranus, and Neptune, also exhibit extraterrestrial auroras, albeit in non-visible spectra.
- Solar storms triggering auroras on planets like Earth, Mars, and Venus have become more common during the peak of the sun's activity cycle.
- Mars' limited atmosphere still has enough gas to emit colorful auroras, despite lacking a proper magnetic field to shield it from solar winds.
