Astronomers discover 2nd fastest asteroid in the solar system hiding in the sun's glare

Astronomers have successfully captured the first direct images of collisions in a nearby star system, providing a glimpse into the violent early history of our solar system when it was less than a billion years old. This groundbreaking achievement allows scientists to observe cosmic events that shaped planetary formation and evolution.

In 2025, solar activity remained high, leading to increased visibility of the northern lights across various regions. As the sun continues its cycle, experts are analyzing how this activity compares to previous years and what it may mean for 2026, particularly regarding the potential for stronger auroras.

NASA's Parker Solar Probe has successfully mapped an unseen part of the sun's atmosphere during its most active phase, marking a significant achievement in solar research. This data provides astronomers with unprecedented insights into solar dynamics and the behavior of solar material.

Astronomers have traced a mysterious 'scar' of ionized gas surrounding the solar system to two stars that had a close flyby with the sun millions of years ago. This discovery sheds light on the dynamic interactions within our galaxy and the historical events that have shaped its structure.

Astronomers have potentially observed the first-ever superkilonova, a rare cosmic explosion resulting from the combination of a supernova and a kilonova. This unprecedented event highlights the complexities of stellar phenomena and the interactions between massive celestial bodies.

A scientist, a journalist, and a scent-detecting dog are investigating the threats facing the last southern resident orcas, a critical community slipping toward extinction. Their efforts highlight the urgent need to understand the factors endangering these orcas, which are vital to marine ecosystems.

Astronomers utilizing the James Webb Space Telescope (JWST) have reported a significant discovery, suggesting that a powerful gamma-ray burst detected in March may have originated from the explosion of a massive star just 730 million years after the Big Bang. This finding could represent the earliest supernova observed in the universe, offering new insights into cosmic events shortly after the universe's formation.
