Using NASA’s Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a triply-eclipsing star system. The newfound system, designated TIC 295741342, consists of two sun-like stars in an eclipsing binary and a giant tertiary companion, which orbits the binary. The finding was reported in a paper published May 19 on the arXiv pre-print server.
Astronomers using the James Webb Space Telescope have uncovered surprising evidence about how enormous “super Jupiter” planets are born.
The discovery blurs the line between massive planets and brown dwarfs, the objects often called failed stars.
Giant gas planets push the limits of planet formation.
Just a few hours before the Orion spacecraft crossed the sky en route to the moon on April 1, mechatronics engineer Rodrigo Trevisan Okamoto received confirmation he had been waiting for since the Artemis 2 mission was announced in 2023. The email from NASA stated that the crew of the first crewed mission to orbit the moon in half a century would carry a device developed by Okamoto and his team at Condor Instruments, a São Paulo-based startup.
“The NASA announcement was sudden and caught us by surprise. And it was only after the mission concluded that we learned the astronauts had been using the equipment in tests for the past two years,” Okamoto told Agência FAPESP.
The device, called an actigraph, is shaped like a wristwatch and incorporates accelerometers, as well as light and temperature sensors, to precisely map the user’s sleep and wake patterns over the course of days or weeks.

The James Webb Space Telescope found galaxies that are too ancient-looking for our young universe. You may have heard that, but it keeps finding them, and our recent efforts to solve this conundrum point in wildly different directions. Have we found galaxies older than the universe, or did we just learn something incredible about how galaxies form?

Lunar Outpost aims to develop a whole ecosystem of infrastructure on the moon, as well as the robots that will build it.
“We’re a lunar infrastructure company, and the infrastructure of the moon base won’t be built by astronauts alone,” the company’s Vice President of Strategy Michael Moreno told Space.com. “It’ll be an autonomous robotic workforce, and that’s our expertise.”
Space.com spoke with Moreno in April 2026 at the Space Foundation’s annual Space Symposium in Colorado Springs about Lunar Outpost’s vision for autonomous technologies that will operate alongside astronauts to build the infrastructure needed for a sustained human presence on the moon.
Astronomers from Italy and Brazil have investigated a nearby red dwarf star known as Ross 318 and have discovered an exoplanet orbiting this star, which is at least six times more massive than Earth. The discovery is reported in a research paper published May 11 on the arXiv preprint server.
Located just 28 light years away from Earth, Ross 318 (also known as Gliese 48, or TIC 379084450) is a red dwarf star of spectral type M3.5V. The star has an orbital period of approximately 51.5 days and an effective temperature of 3,450 K, and showcases strong magnetic activity, which poses a major challenge for exoplanet searches.
A team of astronomers led by Giuseppe Conzo from the amateur astronomy association Gruppo Astrofili Palidoro (GAP) decided to investigate Ross 318, hoping that amidst its magnetic activity, they could verify whether an alien world orbits this star. For this purpose, they conducted a systematic re-analysis of radial velocity (RV) data from the CARMENES spectrograph and decade-long High Resolution Echelle Spectrometer (HIRES) observations. Their study was complemented by data from the Transiting Exoplanet Survey Satellite (TESS).
