Astronomers discover the universe’s missing cosmic matter
- Astronomers have found the missing normal matter in the universe, revealing it as diffuse ionized hydrogen gas surrounding galaxies beyond previous observations.
- This discovery sheds light on galaxy evolution, black hole activity, and gas distribution, potentially resolving conflicts in cosmology.
- The elusive material called warm-hot intergalactic medium (WHIM) was detected using the kinematic Sunyaev-Zel'dovich effect on the cosmic microwave background.
- Ionized gas halos around galaxies suggest supermassive black holes are more active throughout their lifetimes, affecting galaxy formation.
- The findings challenge existing cosmological models and emphasize the need for more accurate simulations to incorporate the extensive gas halos.
- Gas distribution measurements can help address cosmological tensions and improve our understanding of galaxy formation, evolution, and cosmic filaments.
- Future large-scale surveys by observatories like the Vera Rubin Observatory and Nancy Grace Roman Space Telescope will build on these discoveries.
- The research highlights the potential of the kinematic Sunyaev-Zel'dovich effect in studying cosmic structures and advancing our knowledge of the universe.
- By mapping gas distribution around millions of galaxies, astronomers aim to uncover hidden cosmic structures and unravel long-standing astronomical mysteries.
- These breakthroughs could reshape our understanding of the universe by providing new insights into its large-scale structure.
- The study was published online in the journal Physical Review Letters, offering a significant contribution to the field of astronomy and cosmology.

Curiosity rover finds largest carbon chains on Mars from 3.7-billion-year-old rock
- NASA's Curiosity rover discovered long carbon chains in a 3.7 billion-year-old rock sample on Mars, indicating potential evidence for ancient life.
- These molecules containing up to twelve carbon atoms may have originated from fatty acids, suggesting the possibility of past biological activity on Mars.
- The discovery was made by the SAM instrument onboard Curiosity, further hinting at the presence of ancient life on the Red Planet.
- Despite prior analyses, the hydrocarbon strings were accidentally found during a study looking for amino acids in a sample called Cumberland.
- The researchers' new method involving high-temperature pre-heating revealed the presence of these organic molecules in the Martian rock.
- Testing in a lab confirmed that the carbon chains could have derived from fatty acids, suggesting potential life-forming chemistry on Mars.
- The findings boost the possibility of ancient life on Mars and the importance of bringing Martian soil samples back to Earth for further analysis.
- The discovery of carbon chains and their origins as fatty acids signifies Curiosity's capability to detect and preserve ancient organic molecules on Mars.
- Researchers aim to continue studying Mars' geology to unravel the mysteries surrounding potential life on the planet.
- Efforts to bring Martian soil samples to Earth could provide definitive answers regarding the existence of life on Mars.

‘It blew us away’: how an asteroid may have delivered the vital ingredients for life on Earth
- A recent study in Nature revealed that minerals from the asteroid Bennu, collected by the US space probe OSIRIS-REx, contain complex chemicals crucial for life.
- The diversity of molecules and minerals found in the Bennu samples is unique for extraterrestrial samples, according to Prof Sara Russell.
- The upcoming Natural History Museum exhibition will showcase recent developments in the search for life beyond Earth.
- Bennu's material is rich in the basic chemical building blocks necessary for life, hinting at its potential in seeding life on Earth and possibly on other worlds.
- OSIRIS-REx's samples contained phosphates, ammonia, amino acids, and nucleobase building blocks, suggesting asteroid impacts may have delivered ingredients for life on Earth.
- Other promising worlds like Mars and moons of Jupiter and Saturn are being explored for signs of life, with upcoming missions heading towards Europa, Ganymede, Titan, and Enceladus.
- A UK-built Rosalind Franklin robot rover is set to land on Mars in 2029 to search for evidence of life by drilling deep into the soil.
- The exhibition will feature samples of lunar and Martian material, as well as meteorites, including a rock older than Earth itself.
- Recent discoveries on the exoplanet K2-18b, hinting at chemical fingerprints of potential life, have raised hopes for the existence of life beyond Earth.
- The search for alien life will continue, with the possibility of easier study and collection of alien lifeforms within our solar system compared to distant exoplanets.

Curiosity rover reveals ancient carbon cycle on Mars
- NASA's Curiosity rover has uncovered evidence of a robust ancient carbon cycle on Mars, shedding light on the planet's climate history.
- The study, published in Science, found high concentrations of siderite, an iron carbonate mineral, in Martian rock samples collected by the rover.
- These findings challenge prior data and suggest Mars once had a thicker, warmer atmosphere capable of supporting liquid water.
- The presence of siderite hints at large carbon deposits on Mars, hinting at an ancient carbon cycle that may have sustained habitable conditions.
- Scientists believe that Mars had a significantly higher amount of atmospheric CO₂ in the past, with processes like volcanic activity contributing to the planet's climate.
- The discovery of carbonate-rich sediments implies that Mars could have trapped substantial amounts of CO₂, impacting its climate transition over time.
- The identification of iron oxyhydroxides in the sediments suggests that some trapped CO₂ may have been released back into the atmosphere, temporarily delaying Mars' cooling.
- Understanding Mars' ancient carbon cycle provides insights into the planet's habitability over time and may inform future Mars exploration missions.
- The study also offers lessons for Earth's climate, as researchers study Mars' natural carbon storage mechanisms to develop strategies for combating climate change.
- The delicate balance of habitability on Mars serves as a cautionary tale, highlighting the importance of preserving Earth's environment for sustainable life.

Saturn’s moon Titan has rivers—so where did all the deltas go?
- Saturn's moon Titan has rivers and lakes filled with liquid methane and ethane.
- However, unlike Earth, Titan is missing most of its deltas - landforms where rivers meet seas.
- Scientists studied Cassini spacecraft data and found only two likely deltas near the south pole of Titan.
- The absence of deltas on Titan remains a mystery, with possible reasons being fluctuating sea levels or strong winds and tides.
