All supernovae are massively energetic stellar explosions. The classic supernovae are massive stars that explode near the end of their lives, leaving behind either a neutron star or a black hole, and a remnant made of expanding gas and dust. But supernovae are not all the same. Some occur in binary systems, and they're called Type 1a supernovae. As it turns out, some of these Type 1a SNe can detonate twice.

ULA begins stacking its 1st Vulcan rocket supporting a national security mission
United Launch Alliance (ULA) hoists its Vulcan first stage booster into the Vertical Integration Facility-G (VIF-G) adjacent to Space Launch Complex-41 at Cape Canaveral Space Force Station, Florida, on Oct. 22, 2024. The rocket will launch the USSF-106 mission for the U.S. Space Force’s Space Systems Command, Vulcan’s first national security flight. Image: United Launch Alliance
A little more than a week after its most recent Atlas 5 rocket launch, United Launch Alliance rolled a Vulcan booster to the Vertical Integration Facility at Cape Canaveral Space Force Station in Florida on Wednesday morning to begin stacking its first post-certification Vulcan rocket.

In the Search for Earth-like Worlds, We Should Probably Focus on Red Dwarfs
When astronomers first discovered exoplanets, they found massive ones orbiting large stars. The technology to detect smaller planets around low-mass, dim red dwarfs took time to develop. By the mid-2000s, HARPS (High Accuracy Radial velocity Planet Searcher) was specifically targeting M dwarfs and in 2009 discovered the least massive exoplanet at the time.
Weather Satellites Can Even Study the Weather Over on Venus
In 2014 and 2016, the Himawari-8 and -9 satellites were launched into orbit. Owned and operated by the Japan Meteorological Agency (JMA), these satellites monitor global weather patterns and atmospheric phenomena using their multispectral Advanced Himawari Imagers (AHIs). In a recent study, a team led by the University of Tokyo presented infrared images that capture changes in Venus' atmosphere, revealing unseen temperature patterns in its cloud tops. The results show that meteorological satellites can complement observations of Venus' atmosphere by robotic missions and ground-based telescopes.

Tianwen-2 Looks Back at the Earth
China's Tianwen-2 probe continues on its journey to rendezvous with a Near-Earth Asteroid (NEA) before heading to the Main Asteroid Belt. The second in China's interplanetary exploration program (which translates to "Questions to Heaven"), this mission will obtain samples from asteroid 469219 Kamoʻoalewa and return them to Earth. From there, China plans to send the probe to rendezvous with the Main Belt comet 311P/PANSTARRS to explore it using its 11 onboard instruments. Yesterday, the Chinese National Space Agency (CNSA) released images the probe took of Earth and the Moon.
