Scientists say strange gases could be signs of alien life
- Scientists from the University of California, Riverside are searching for signs of alien life by looking for unusual gases in the atmospheres of distant planets.
- Their focus is on methyl halides, gases mostly produced by bacteria, algae, fungi, and some plants on Earth.
- Hycean planets, hot, ocean-covered planets with thick hydrogen atmospheres, are seen as good candidates for harboring these gases, and the James Webb Space Telescope (JWST) will be used for detection.
- If these gases are detected, it could imply the existence of anaerobic microbes and suggest that life is more common in the universe than previously thought.

Live coverage: SpaceX to launch national security satellite for NRO on Falcon 9 rocket from Cape Canaveral
- SpaceX is set to launch the NROL-69 mission for the National Reconnaissance Office on a Falcon 9 rocket from Cape Canaveral Space Force Station.
- The mission is the fifth for the NRO out of roughly a dozen planned for the year, with liftoff scheduled for 1:48 p.m. EDT (1748 UTC).
- The 45th Weather Squadron predicts a 90 percent chance of favorable weather for the launch.
- SpaceX plans to reuse the Falcon 9 first stage booster B1092, which previously launched the Starlink 12-13 flight.
- The mission will see the booster attempting to land back at Landing Zone 1, marking the 50th touchdown at LZ-1 and the 422nd booster landing overall if successful.
- NROL-69 is part of the National Security Space Launch program Phase 2, with SpaceX and ULA being awarded contracts worth billions of dollars.
- The NRO provides limited details about its missions, including payload information, with a national security payload onboard the Falcon 9 for this launch.
- The Falcon 9 rocket's second stage features a grey band, indicating potential measures for keeping the rocket's propellant at a consistent temperature during long coast phases.
- SpaceX's strategic use of different configurations like medium-coast kits for second stages is highlighted, optimizing performance and system operations during spaceflight.
- The protective grey stripe on the rocket's second stage was also seen during previous launches, aiding in maintaining the necessary fuel temperature for mission success.

Which states will see the March 29 solar eclipse — and which will see a 'double sunrise'?
- Thirteen U.S. states will see the March 29 solar eclipse in some form, with a deeper eclipse visible the farther northeast you go.
- In Maine, up to 86% of the sun will be eclipsed as it rises, while New Hampshire and Massachusetts will see up to 57% and 55% coverage respectively. Boston will experience a 43% eclipse.
- Viewers must use protective eyewear at all times as this is a partial eclipse.
- In some locations, a 'double sunrise' will be visible, where the silhouette of the moon makes the rising sun look like two separate 'horns' emerging from the horizon.

Astronomers discover mysterious filaments near Milky Way’s center
- Astronomers have discovered long, thin 'space tornadoes' near the center of the Milky Way galaxy.
- These filaments, made of swirling gas, were found using the ALMA telescope in Chile.
- The filaments are created by violent shocks moving through space, and they help circulate materials around the galactic center.
- Further studies and simulations are needed to fully understand these space tornadoes and their role in our galaxy.

Amazing iguanas conquered Fiji after a 5,000-mile journey
- Researchers have discovered that iguanas in Fiji and Tonga likely arrived on the islands by rafting from western North America, traveling 5,000 miles across the Pacific Ocean.
- The iguanas arrived on the islands around 34 million years ago, making them the longest known transoceanic dispersal of any non-human terrestrial vertebrate.
- These iguanas belong to the genus Brachylophus and are closely related to iguanas of the genus Dipsosaurus, particularly the North American desert iguana.
- The study confirms that the iguanas colonized Fiji and Tonga from North America, diverging from Dipsosaurus iguanas around 30 million years ago when volcanic activity could have produced land.
- The journey of the iguanas showcases their resilience and ability to survive long periods without food or water, likely traveling on rafts made of fallen trees and plants.
- The iguanas' dispersal over water contributed to the evolution of new species and ecosystems, with Fiji and Tonga hosting these unique reptiles, now listed as critically endangered.
- The unique journey of the iguanas sheds light on the incredible adaptations of these reptiles and their ability to conquer distant islands through transoceanic dispersal.
- The discovery highlights the importance of understanding the origins and colonization patterns of different species, offering insights into the evolutionary history of iguanas.
- Despite facing threats such as habitat loss and exploitation by smugglers, the iguanas of Fiji and Tonga remain a testament to the remarkable journeys undertaken by wildlife in the natural world.
- This study, published in the Proceedings of the National Academy of Sciences, expands our understanding of how iguanas conquered remote islands and the challenges they face in their unique habitats.

Intelligent aliens would need a power supply to jump-start their civilization — would they require fossil fuels?
- Intelligent aliens building a civilization would likely require a source of energy as abundant as fossil fuels.
- Aliens may need to follow a similar path as humans in utilizing fossil fuels initially, due to the energy requirements for industrialization.
- The production of alternative energy sources like solar panels also demands significant energy input, creating a dilemma.
- While aliens could start by burning materials for fuel, they might eventually harness starlight or wind energy for more sustainable sources.
- However, wind energy alone may not generate the high temperatures necessary for industrial processes like metalworking.
- Hydropower could be a viable option if the alien planet has significant accessible liquid, which is uncommon in planets observed so far.
- The presence of fossil fuels on a planet correlates with plate tectonics regulating climate and creating conditions for life to evolve and transform into fuels.
- Active plate tectonics contribute to the formation of fossil fuels like coal over millions of years by creating ideal conditions for life and fuel production.
- Scientists have yet to find another planet with active plate tectonics or fossil fuels, but evidence of fuel components like hydrogen and carbon exists in space.
- Aliens may have access to elements like liquid hydrocarbons on moons, such as Saturn's Titan, which could potentially serve as fuel sources.

Saturn’s Rings to “Disappear”
- Saturn’s iconic rings are set to seemingly vanish from view this weekend as they align edge-on with Earth for the first time since 2009.
- Every 13 to 15 years, Saturn’s rings align perfectly with our line of sight, making them appear nearly invisible from Earth.
- Saturn's rings will slowly begin to tilt back toward Earth, appearing as a thin line before gradually becoming more visible in the coming months.
- If you miss this opportunity, mark your calendar for September 21, 2025 for a chance to observe Saturn's rings at their brightest.

Wolf-Rayet 104: The “pinwheel star” isn’t a death star after all
- Astronomers have discovered that Wolf-Rayet 104 is made up of two massive stars orbiting each other every 8 months.
- The stars' powerful stellar winds collide, creating a spiral of dust that glows in infrared light and spins like a cosmic pinwheel.
- The system was previously thought to be potentially aiming a deadly gamma-ray burst (GRB) towards Earth, but new research reveals that the dust spiral is tilted differently from the stars' orbit, reducing the chance of a GRB hitting Earth.
- While the discovery is reassuring, it also raises new questions about the unknown forces and processes shaping the dust spiral.
