Gaia data maps variable stars across Milky Way clusters
Using data from the European Space Agency's Gaia mission, Richard I. Anderson of EPFL and Emily Hunt of the Max Planck Institute for Astronomy produced the first galaxy-scale map linking variable stars to their host open clusters, tallying nearly 35,000 variables in 1,200 clusters. The study appears as a Letter in Astronomy and Astrophysics.
Open clusters serve as natural laboratories beca NASA's PUNCH Mission Reaches Science Orbit, Releases Data
All four spacecraft of NASA's PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission have successfully maneuvered into their final science orbits as of Aug 7.
Launched into Earth orbit on March 11, PUNCH's four suitcase-sized spacecraft are now spread out along the planet's day-night boundary, giving the mission a continuous, unobstructed view of the Sun and its surroundings. This TRAPPIST-1 d ruled out as Earth twin by Webb study
Astronomers have determined that TRAPPIST-1 d, a rocky exoplanet similar in size to Earth and located in a potentially temperate zone, lacks an Earth-like atmosphere based on new NASA/ESA/CSA James Webb Space Telescope data.
The finding narrows the search for worlds with conditions similar to Earth, according to lead author Caroline Piaulet-Ghorayeb of the University of Chicago and Univers Preparing rock analysis methods on Earth for future Mars samples
In 2024, NASA's Mars rover Perseverance retrieved an unusual specimen named Sapphire Canyon, a red mudstone with white, black-edged spots that could reveal potential sources of organic molecules on the planet.
To prepare for its eventual return, scientists from NASA's Jet Propulsion Laboratory and Caltech tested optical photothermal infrared spectroscopy (O-PTIR) on an Earth rock with simi Signs of recent life on Mars could be detected using new simple test
A PhD student and his supervisor have developed a simple way for testing for active life on Mars and other planets using equipment already on the Mars Curiosity rover and planned for future use on the ExoMars Rosalind Franklin rover.
There is enormous interest in the possibility of past or present life beyond Earth, with space agencies spending a great deal of time and money exploring suit NASA seeks student entries for Human Exploration Rover Challenge
NASA is accepting contest entries from student teams to design, build and test rovers on the moon and Mars.
In the Human Exploration Rover Challenge, students need to make models that are capable of going over a course while completing tasks for future Artemis missions, NASA said in a news release.
In the challenge, teams design projects that sample of soil, water and air over a After repeated explosions, new test for Musk's megarocket
