Climate Change Is Making Space More Hazardous for Satellites
- Greenhouse gas emissions are affecting the thermosphere, which extends into low Earth orbit where satellites operate.
- CO2 in the upper atmosphere radiates heat away, causing the thermosphere to cool and contract, impacting satellite operations.
- This long-term shift in the thermosphere due to greenhouse gas emissions affects atmospheric density and space debris.
- Reduced atmospheric drag because of thermosphere contraction increases the risk of collisions and creates more space debris.
- The rapid increase in satellite numbers, particularly with megaconstellations like SpaceX's Starlink, heightens collision risks.
- MIT study suggests that greenhouse gas-induced atmospheric changes could reduce safe satellite operation by 50-66% by 2100.
- Runaway collisions known as the Kessler syndrome could render space unusable if emissions continue to rise unchecked.
- Urgent need for sustainable space operations to prevent a crowded and hazardous space environment in the future.
- International efforts to regulate satellite deployment and limit emissions are crucial to ensure space sustainability.
- Research highlights the interconnectivity between Earth's climate and space sustainability, emphasizing the need to address greenhouse gas emissions.

A giant extraterrestrial 'wave' hit Earth 14 million years ago — and may have dramatically altered our planet's climate
- A study suggests that around 14 million years ago, our solar system passed through a dense, star-forming region in the direction of the constellation Orion, which may have impacted Earth's climate.
- This region, named the Radcliffe Wave, could have increased the flow of interstellar dust to Earth, coinciding with Earth's transition to a cooler climate and the expansion of the Antarctic Ice Sheet.
- Spotting evidence of this event, such as a spike in the abundance of iron-60, in Earth's geological record could support the hypothesis.
- Research indicates our solar system was closest to the Orion region and dust-heavy star clusters around 14 million years ago.
- Simulations suggest that the dense region may have blocked some of the sun's radiation, contributing to planet-wide cooling during Earth's 'Middle Miocene' transition.
- The study's claim of galactic influences on Earth's climate is intriguing, but further assessments are needed to evaluate its likelihood.
- Although there are challenges in detecting signals from events 14 million years ago, advances in instrumentation and analysis techniques could aid future investigations.
- Astronomers and geologists may focus on potential solar-system-wide evidence, such as deep moon craters, to further explore the effects of extraterrestrial influences.
- Understanding the impact of extraterrestrial events on Earth's climate could shed light on past climatic shifts and help in deciphering the complexities of current climate change processes.
- The study highlights the need for interdisciplinary collaboration across sciences to investigate the possible interaction between cosmic events and Earth's climate history.

Remains of destroyed planet found lurking in Helix nebula
- Astronomers have detected unusual X-ray signals coming from the center of the Helix nebula since 1980, with a new study suggesting they may be from a destroyed planet falling onto the white dwarf star at the nebula's center.
- The Helix nebula is a planetary nebula formed from the outer layers of a star that became a white dwarf, with the X-rays coming from debris of a destroyed planet falling onto the white dwarf.
- Researchers believe the X-ray signals observed in the Helix nebula for over 40 years could be due to remnants of a Jupiter-sized planet that was destroyed by the white dwarf.
- The destroyed planet likely fell into the white dwarf after migrating closer to it, with the debris heating up and emitting X-ray signals, providing a possible explanation for the mysterious X-ray emissions.
- Other similar white dwarfs have also been found to interact with destroyed or disintegrating planets, shedding light on how planets evolve in the vicinity of aging stars like white dwarfs.
- The discovery of the destroyed planet in the Helix nebula sheds new insights into the dynamics of planetary systems around white dwarfs and their survival as stars age.
- Understanding how planets are affected by aging stars like white dwarfs can provide valuable information about the fate of planets, including possible habitability, in such systems.
- The findings from the study published in the Monthly Notices of the Royal Astronomical Society suggest that the destroyed planet's remains continue to orbit the white dwarf, contributing to the X-ray emissions.
- A destroyed planet near a white dwarf in the Helix nebula is a rare discovery, offering unique insights into the interactions between planets and aging stars, providing vital information about planetary survival in such environments.
- The study's findings help astronomers unravel the mysteries of X-ray emissions in the Helix nebula, linking them to the remnants of a destroyed planet, showcasing the complexities of planetary systems in the universe.
