What is the importance of studying explosive volcanism on Venus? This is what a recent study published in the *Journal of Geophysical Research: Planets* hopes to address as a team of scientists investigated the potential altitudes of explosive volcanism on Venus. This study has the potential to help scientists better understand the present volcanic activity on Venus, along with gaining insight about its formation and evolution and other planetary bodies throughout the solar system and beyond.

HydroGNSS launch highlights
Video: 00:02:51
ESA’s first Scout mission, HydroGNSS, was launched on 28 November 2025, marking a significant step in advancing global understanding of water availability and the effects of climate change on Earth’s water cycle.
First Private Space Telescope Launches Successfully
A small space telescope may signal a big new trend for modern astronomy.

Update Nov. 28, 5:45 p.m. EST (2345 UTC): SpaceX deployed all payloads designed to separate from the rocket.
Nancy Grace Roman Has Been Shaken, Frozen, and Screamed At. Now It's Ready For Its Next Round of Tests
The Nancy Grace Roman Space Telescope continues its inexorable march toward launch. It recently completed another series of tests that brings it a few steps closer to a launch pad in Florida. This time, the telescope was split into two separate parts - an inner portion and an outer portion, each of which went through separate tests throughout the fall.
This Week's Sky at a Glance, November 28 – December 7
Saturn remains super-thin-ringed high after dark. The interstellar comet, 11th magnitude, is now nice and high in the dark before dawn. Don't wait; moonlight approaches.

Massive Computer Simulation Creates a Hyper-Realistic Model of the Milky Way
Researchers at the RIKEN Center for Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS) in Japan recently accomplished something truly unprecedented. With the help of colleagues from the University of Tokyo and the Universitat de Barcelona, the team conducted the world's first Milky Way simulations that accurately represented more than 100 billion stars over 10,000 years. The simulation not only represented 100 times more individual stars than previous models, but was also produced 100 times faster.
Galaxies Struggle To Grow In Crowded Environments
The evolution of each individual galaxy is shaped by its surroundings, according to new research. The Deep Extragalactic Visible Legacy Survey (DEVILS), an endeavour of ICRAR and the University of Western Australia, has released its first data. It includes catalogues of morphological, redshift, photometric and spectroscopic data, as well as group environments and halo data for thousands of galaxies.
The Star That Shouldn't Exist
Studying the light from stars tells us their temperature, composition, age, and evolutionary state. But the red giant companion to Gaia BH2, a black hole system discovered in 2023, tells a contradictory story that doesn't make sense until you consider stellar violence!
After a Century of Searching, We May Have Finally Seen Dark Matter
I once filmed down a salt mine in North Yorkshire, descending into a dark matter laboratory buried deep underground where scientists wait for the rarest of collisions, dark matter particles interacting with ordinary matter. They're still waiting. But above ground, looking outward rather than inward, Professor Tomonori Totani from the University of Tokyo may have found what those underground detectors haven’t, dark matter revealing itself through light.
Devastating Stellar Storm Seen on Red Dwarf Star
A first ever detection of a coronal mass ejection from a small red dwarf could have big consequences for life on any nearby planets.

Earth observation company BlackSky revealed it was the ‘confidential customer’ whose satellite flew on a recent Rocket Lab Electron rocket. A BlackSky spokesperson confirmed to Spaceflight Now on Tuesday that its Gen-3 satellite was the payload onboard.
Age of the Universe
The age of the Universe is a fundamental parameter in cosmology, representing the time elapsed since the Big Bang. Current scientific consensus, based primarily on observations of the Cosmic Microwave Background (CMB) and the expansion rate of the Universe, places this age at approximately 13.8 billion years.
