Unveiling mysteries of the universe

Chinese scientists have identified a gamma-ray spectral line with energy levels peaking at 37 million electron volts. Interestingly, the gamma-ray line evolves according to a power-law function over time, providing clues to the mystery of the line. This significant discovery marks a major milestone in the field of gamma-ray burst research.

Mars exploration

NASA has found possible signs of ancient life on Mars. Its Perseverance rover has come across a vein-filled red rock that reveals signs of organic material. The rock displays intriguing surface spots similar to those associated with fossilized microbes on Earth, and there is evidence that water once passed through the rock. More studies are needed, but this discovery could help scientists unlock the secrets to life on Mars.

Climate change

Earth recorded its hottest day in history on July 21, when the daily global average temperature touched 17.09 degree Celsius. This record was broken within a day, as that average temperature rose to 17.15 degrees Celsius on July 22. Scientists attribute this heat to human-caused global warming. They say the planet may see its warmest period in at least 100,000 years.

Space mission

SpaceX and NASA plan to launch the Crew-9 mission to the International Space Station (ISS) on August 18. This will be the ninth crew rotation to the ISS. The mission will include four NASA astronauts. They will be launched aboard a SpaceX Dragon spacecraft, propelled by the Falcon 9 rocket. The rocket was temporarily grounded due to a mid-flight failure earlier this month, but has since been cleared.
