The exploration of celestial bodies and cosmic phenomena beyond Earth. This field seeks to uncover the mysteries of the universe, including the nature of stars, planets, galaxies, and the laws governing space and time.
At the EPSC-DPS2025 Joint Meeting in Helsinki, scientists reported that Mars’s north polar vortex traps air about 40°C (72°F) colder than its surroundings, creating conditions for ozone to build up in the darkness of winter.
An international team led by São Paulo State University (UNESP) researchers report that undetected asteroids sharing Venus’s orbit may one day cross Earth’s path, posing long-term impact risks.
A study published in Space Weather confirms that the Centennial Gleissberg Cycle has passed its minimum, ending a 15-year quiet phase and forecasting stronger solar cycles through mid-century.
NASA analysis confirms the Sun’s activity, which had weakened since the 1980s and reached record lows in 2008, has been rising again through the past 17 years, a reversal with wide implications for space weather, Earth’s technology, and our understanding of long-term solar behavior.
Astronauts are expected to travel around the Moon for the first time in more than 50 years during NASA’s Artemis II mission, scheduled for 2026. The crew will orbit the Moon aboard the Orion spacecraft, providing data on the effects of deep space travel on humans that will guide planning for future missions.
European Space Agency (ESA) released a new three-dimensional map of stellar nurseries within 4 000 light-years (1 225 parsecs) of the Sun, built from Gaia mission data and advanced simulations. The map, the most detailed of its kind, reveals how massive stars carve vast cavities in interstellar gas and provides fresh insight into the Milky Way’s recent star-forming history.
A study published in Research Notes of the American Astronomical Society this month confirmed asteroid 2025 PN7 as Earth’s smallest and most unstable quasi-moon. While this asteroid was detected just over a month ago, observations suggest it’s been with us for about 70 years and is expected to remain a quasi-satellite orbit for another 128 years.
Astronomers may have uncovered evidence of a hidden world – “Planet Y” – whose gravity could be warping the Kuiper Belt. If confirmed, it would represent a new addition to the solar system, distinct from the debated Planet Nine.
The James Webb Space Telescope detected an 8-light-year stellar jet in the Sharpless 2-284 nebula, located 15 000 light-years from Earth in the outer Milky Way, according to a study accepted in The Astrophysical Journal on September 10, 2025.
Liquid water flowed on the parent body of asteroid Ryugu more than 1 billion years after its formation, according to a study published on September 11, 2025, based on Hayabusa2 mission samples.
