A team of astronomers has used observations from the Hobby-Eberly Telescope (HET) at The University of Texas at Austin's McDonald Observatory to discover some of the longest tails of gas yet observed escaping a planet. The planet, HAT-P-32b, is nearly twice the size of Jupiter and losing its atmosphere through dramatic jets of helium unfurling before and behind it as it travels through spa

ESA's exoplanet mission Cheops confirmed the existence of four warm exoplanets orbiting four stars in our Milky Way. These exoplanets have sizes between Earth and Neptune and orbit their stars closer than Mercury our Sun. These so-called mini-Neptunes are unlike any planet in our Solar System and provide a 'missing link' between Earth-like and Neptune-like planets that is not yet understoo

A new study led by Chinese scientists has confirmed the existence of first-generation stars with 260 solar masses for the first time by finding evidence of the existence of pair-instability supernovae (PISNe) which evolved from such massive first stars in the early universe. Previously, studies had only confirmed the existence of first-generation stars of under 100 solar masses, and thus t

The movement of cosmic ray particles across space, such as electrons and protons, is influenced by the Sun's magnetic field, causing fluctuations in the intensity of galactic cosmic rays (GCRs) reaching Earth in response to the solar cycle. During periods of low solar activity, such as the solar minimum, more GCRs have been observed to reach Earth compared to that for periods of high solar activ

HawkEye 360 Inc., the world's leading defense technology company for space-based radio frequency (RF) data and analytics, reports that its Cluster 7 satellites have begun operation. This latest satellite trio achieved initial operating capability in record time after successfully launching into orbit on April 15, 2023. A new 300MHz whip antenna provides better coverage in the 270MHz - 330M

Spirent will demonstrate the first fully-certified Xona satellite constellation simulator, SimXona, at the 2023 Joint Navigation Conference (JNC), June 12-15, 2023, in San Diego, CA. Organized by the Institute of Navigation, JNC is the largest U.S. military positioning, navigation, and timing (PNT) conference, with government, defense, and industry participation. Spirent, the leading globa

E-Space has completed a five-month feasibility study, commissioned by the French Space Agency, Centre National D'Etudes Spatiales (CNES). The study aimed at assessing and validating the technical capabilities of the E-Space satellite system (space platform, communication payload, guidance, navigation and control (GNC) and user terminal) as well as the long-term viability of the Company's underly

As we enter a new era in space travel, a study looking at how the human brain reacts to traveling outside Earth's gravity suggests frequent flyers should wait three years after longer missions to allow the physiological changes in their brains to reset. Researchers studied brain scans of 30 astronauts from before and after space travel. Their findings, reported in Scientific Reports, revea

China is working on a rocket for its moon landing mission, which will send a manned spaceship and a lander to lunar orbit in two separate flights, chief designer of the country's manned space program Zhou Jianping revealed. The spaceship will send the taikonauts to lunar orbit and dock with the lunar lander. The lander will subsequently carry the taikonauts to the moon's surface. After the
