New study challenges existing models of the universe’s expansion
A new study has confirmed that the universe is expanding faster than previously thought, deepening the Hubble constant discrepancy.
First evidence of helical magnetic field in HH 80-81 protostellar jets
Scientists reported the first-ever evidence of a helical magnetic field within HH 80-81 protostellar jet on January 7, 2025, using data from the Karl G. Jansky Very Large Array (VLA). It is the first time a Rotation Measure (RM) analysis has been performed on a protostellar jet.
Parker Solar Probe confirms safe status after record-breaking solar encounter
NASA’s Parker Solar Probe confirmed its systems and instruments are fully operational after completing its closest-ever approach to the Sun on December 24, 2024.
Parker Solar Probe makes closest approach to Sun on Christmas Eve as fastest man-made object ever
NASA’s Parker Solar Probe made its closest approach to the Sun at 11:53 UTC on December 24, 2024, coming within 6.1 million km (3.8 million miles) of its surface. Traveling at a remarkable speed of 700 000 km/h (435 000 mph), it set a record as the fastest human-made object in history. The probe’s next transmission is expected on December 27 to report its health after the perihelion.
Mysterious fast radio bursts may originate from asteroid collisions with neutron stars
Fast radio bursts (FRBs) might originate from collisions between asteroids and neutron stars, researchers from the University of Toronto, the University of Oxford, and the University of Canterbury announced on November 15, 2024.
Astronomers discover smallest main belt asteroids
MIT astronomers, using NASA’s JWST, discovered 138 small asteroids in the main belt between Mars and Jupiter on December 9, 2024. Some of these asteroids are as small as 10 m (33 feet) wide which makes them the smallest ever found in this region.
Decade-long survey shows effects of South Atlantic Anomaly on ESA’s Swarm satellites
A decade-long survey conducted by teams from ESA and Airbus reveals how space radiation over the South Atlantic Anomaly (SAA) affected the onboard memory systems of ESA’s Swarm constellation, a trio of satellites mapping Earth’s magnetic field since 2013.
April 8 total solar eclipse reveals changes in the Sun’s corona and Earth’s atmosphere
Scientists presenting at the American Geophysical Union (AGU) meeting in Washington, D.C., on December 10, 2024 revealed detailed changes in the Sun’s corona and Earth’s atmosphere during the solar eclipse on April 8, 2024.
Twin spacecraft Proba-3 launched on unique mission to create artificial solar eclipses
Two European satellites were launched from India’s Satish Dhawan Space Center on December 5, 2024, as part of ESA’s Proba-3 mission, marking a new chapter in solar corona research.
