Scientists detected an extremely high-energy cosmic ray beaming from outer space — which confusingly came from nowhere in particular.

Worlds orbiting a sun-like star 100 light-years from Earth could unlock secrets surrounding the formation of our solar system.
They are the most common type of planet observed in our Milky Way galaxy — two to three times the diameter of Earth but smaller than Neptune, and orbiting closer to their stars than our solar system’s innermost planet Mercury does to the sun.
The European Space Agency (ESA) has a number of missions ongoing to discover and study exoplanets, which are planets outside of our solar system.
One of those missions, Cheops (CHaracterising ExOPlanet Satellite), has uncovered a rare star system that lies around 100 light-years away.
It’s an important find because it can tell us about the formation and evolution of the planetary system, according to ESA.
The U.S. Naval Research Laboratory (NRL), in conjunction with the international Fermi Large Area Telescope Collaboration, announce the discovery of nearly 300 gamma ray pulsars in the publication of their Third Catalog of Gamma Ray Pulsars. This milestone comes 15 years after the launch of Fermi in 2008 when there were fewer than ten known gamma-ray pulsars.
“Work on this important catalog has been going on in our group for years,” said Paul Ray, Ph.D., head of the High Energy Astrophysics and Applications Section at NRL. “Our scientists and postdocs have been able to both discover and analyze the timing behavior and spectra of many of these newfound pulsars as part of our quest to further our understanding of these exotic stars that we are able to use as cosmic clocks.”
Pulsars are formed when massive stars have burned through their fuel supply and become unable to resist the inward pull of their own gravity. This results in the star collapsing into a dense, spinning, magnetized neutron star. Their spinning magnetic fields send out beams of gamma rays, the most energetic form of light. As these beams sweep across the Earth, the highly sensitive Fermi gamma-ray telescope can observe their periodic energy pulses. With more than 15 years of data, Fermi has transformed the field of pulsar research.
NASA revealed multiple new panoramic images of clouds and dust in Mars’ skies and one of its two tiny moons taken by the spacecraft last May. They were captured by the Odyssey’s camera, called the Thermal Emission Imaging System, or THEMIS.
The rare images were taken from an altitude of about 250 miles, the same altitude at which the International Space Station flies above Earth, according to NASA.
“If there were astronauts in orbit over Mars, this is the perspective they would have,” said Jonathon Hill, the operations lead of THEMIS. “No Mars spacecraft has ever had this kind of view before.”
Thales Alenia Space is working on the creation of a lunar module called the Multi-Purpose Habitat (MPH).

NASA is actively seeking technological solutions to construct a safe haven for future astronauts as well as investigate the feasibility of long-term settlements.
Space Warfare concepts from science fiction often involve war between planets, and we will discuss the science of that, and war inside a fully colonized solar system or Dyson Swarm.

The Enabling Technologies Programme (ETP) provides opportunities for the UK space sector to accelerate the development of leading-edge technologies that could be used to tackle global problems and benefit the work of space organisations internationally.
The total government funding is £4 million — made up of £3.2 million from the UK Space Agency with £800,000 contributed by the Science and Technology Facilities Council (STFC), part of UK Research and Innovation (UKRI).
The projects from academia and industry explore how space can be used more efficiently for purposes such as weather prediction, climate-change monitoring, and space debris removal through methods of propulsion, sterilisation, in-orbit servicing, imaging, and more.
