ESA Industry Space Days Returns to ESTEC in September 2026 The European Space Agency will host its biennial Industry Space Days (ISD) on 16-17 September 2026 at ESA’s technical center ESTEC in Noordwijk, Netherlands. The event serves as a business-to-business meeting point for Europe’s space sector, bringing together established prime contractors, small and medium enterprises, […]

NASA’s Juno spacecraft has produced the first measurements of temperature beneath the surface of Io, Jupiter’s innermost Galilean moon and the most volcanically active body in the solar system. The data, collected during two close flybys and published in the Journal of Geophysical Research: Planets on July 22, 2026, reveal a temperature increase of more […]

ESA Industry Space Days: European Space Startups Take Center Stage The European Space Agency will host its Industry Space Days (ISD) event on 16-17 September 2026 at ESA’s technical center ESTEC in Noordwijk, Netherlands, putting a spotlight on the continent’s rapidly expanding startup ecosystem. The biennial gathering brings together Europe’s space industry for two days […]

Revisiting Primordial Black Hole Accretion, Evaporation, and Cosmological Consequences Primordial black holes occupy a peculiar place in cosmology. Unlike the supermassive black holes that anchor galaxies or the stellar-mass black holes born from collapsing stars, PBHs would have formed in the first chaotic fractions of a second after the Big Bang. Dense pockets of energy […]

SpaceX sent its Starship megarocket skyward for the 13th time on July 24, achieving several milestones that brought the company closer to operational use of the world’s most powerful launch vehicle. Liftoff from Starbase in Boca Chica, Texas, came at 5:51 p.m. Central time after a previous attempt on July 16 was aborted by onboard […]

The most common type of planet in the Milky Way may be hiding a secret beneath its hazy outer layers. Sub-Neptunes, worlds slightly smaller than Neptune but lacking a solid surface in the familiar sense, account for roughly 3,300 of the more than 6,300 confirmed exoplanets. Yet they remain among the least understood planetary bodies […]

Black holes are among the most extreme objects in the universe, but they are not all the same. Astronomers sort them into four broad categories based primarily on mass: stellar-mass, intermediate-mass, supermassive, and the still-theoretical primordial black holes. Each type tells a different story about how the universe builds structure across cosmic time. Stellar-mass black […]

Expedition 74 Trio Returns to Earth After 241 Days in Orbit July 26, 2026—A Soyuz spacecraft carrying a NASA astronaut and two Russian cosmonauts touched down on the steppe of Kazakhstan early Sunday, wrapping up a 241-day research mission aboard the International Space Station. The Soyuz MS-28 capsule landed at 10:27 UTC (3:27 p.m. local […]

Astronomers have delivered a reality check on the hunt for hidden black holes and neutron stars in the Milky Way. A team led by Joshua Simon of the Carnegie Observatories conducted spectroscopic follow-up on 31 binary star systems that Gaia, the European Space Agency’s star-mapping satellite, had flagged as possible homes for dark compact objects. […]

Blue Origin to Fire New Glenn Upper Stage on Historic Apollo-Era Test Stand Under NASA Deal NASA and Blue Origin have formalized an agreement to conduct hot-fire testing of the New Glenn rocket’s second stage on the B-2 test stand at NASA’s Stennis Space Center in Mississippi, the agency confirmed this week. The arrangement, an […]
