The discovery potentially transforms what we think about how the cosmic environment influences galaxies as they form.
Stars form in massive clouds of gas called molecular clouds. As they form, they accrete gas from these clouds, and as the stars rotate, gas and dust accumulates in a rotating disk around the star called a protoplanetary disk. As the name makes clear, this is where planets form by accreting material from the disk.
In the fields of science and science communication, there are few things more controversial than claims regarding the discovery of extraterrestrial life. This includes claims ranging from the discovery of the most basic lifeforms (lichens, single-celled organisms, etc.) to evidence of advanced civilizations. Such claims are incredibly common, thanks to the sensationalism surrounding the Search for Extraterrestrial Intelligence (SETI) and the search for life beyond Earth (astrobiology). Even when scientists have avoided issuing declarative judgments, it is very easy for statements to be twisted and misrepresented.
As he did eight months ago, Sen. Ed Markey asked Jared Isaacman if Elon Musk was in the room when President Trump first offered him the job of NASA chief. And, once again, Isaacman demurred.
The groundbreaking mission designed to observe our Sun and its interactions with Earth celebrates three decades in space this week.
Levels of potentially dangerous cosmic radiation in Earth's atmosphere rose to a two-decade high in November after a rare solar super-flare pummeled the planet with high-speed particles from the sun.
If you've never sighted this rocky little world for yourself, you'll never get a better opportunity than right now to see it.
Jupiter has numerous moons, with the four largest being Io, Europa, Ganymede, and Callisto. These four, often referred to as the Galilean moons after their discoverer Galileo Galilei, are among the most fascinating objects in the solar system.

A mishap during the successful Nov. 27 launch of three astronauts damaged the only pad that currently supports Russian crewed orbital liftoffs. How long before things are back up and running again?

The Geminid meteor shower is active from Dec. 4 and hits its peak on the night of Dec. 13-14.
Technicians with NASA’s Exploration Ground Systems team use a crane to lift and secure NASA’s Orion spacecraft on top of the SLS (Space Launch System) rocket in High Bay 3 of the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Saturday, Oct. 18, 2025, for the agency’s Artemis 2 mission.

The four astronauts who are to fly a loop around the Moon next year on the Artemis 2 mission were supposed to board their Orion capsule on Nov. 19 for a launch day rehearsal, but a problem with the spacecraft’s hatch delayed the practice run, NASA told Spaceflight Now.
The EURECA spacecraft flew on the space shuttle Atlantis in 1992.
A new joint analysis from the NOvA and T2K experiments offers the most precise look yet at neutrino behavior, bringing scientists closer to understanding why the universe is made of matter.
An idea for the stubborn winter stargazer on your holiday list (especially if it's you!)
Searching for technosignatures - signs of technology on a planet that we can see from afr - remains a difficult task. There are so many different factors to consider, and we only have the technological capabilities to detect a relatively small collection of them. A new paper, available in pre-print on arXiv but also accepted for publication into The Astrophysical Journal Letters, from Jacob Haqq-Misra of the Blue Marble Space Institute of Science and his co-authors explores some of those capabilities by using a framework they developed known as Project Janus that estimates what technology will look like on Earth 1,000 years from now in the hopes that we can test whether or not we can detect it on another planet.

What can an exoplanet leaking helium teach astronomers about the formation and evolution of exoplanet atmospheres? This is what a recent study published in *Nature Astronomy* hopes to address as an international team of scientists investigated atmospheric escape on a puffy exoplanet. This study has the potential to help scientists better understand the formation and evolution of gas giant planets, specifically with many gas giant planets observed orbiting extremely close to their stars.
