NASA's Webb identifies the earliest strands of the cosmic web

Galaxies are not scattered randomly across the universe. They gather together not only into clusters, but into vast interconnected filamentary structures with gigantic barren voids in between. This "cosmic web" started out tenuous and became more distinct over time as gravity drew matter together.

New images from the James Webb Space Telescope have revealed, for the first time, starlight from two massive galaxies hosting actively growing black holes - quasars - seen less than a billion years after the Big Bang. A new study in Nature this week finds the black holes have masses close to a billion times that of the Sun, and the host galaxy masses are almost one hundred times larger, a ratio A simulation finds solutions to a central mystery in space physics

How are plasma eruptions in near-Earth space formed? Vlasiator, a model designed at the University of Helsinki for simulating near-Earth space, demonstrated that the two central theories on the occurrence of eruptions are simultaneously valid: eruptions are explained by both magnetic reconnection and kinetic instabilities.

From visible starlight to radio waves, the Milky Way galaxy has long been observed through the various frequencies of electromagnetic radiation it emits. Scientists have now revealed a uniquely different image of our galaxy by determining the galactic origin of thousands of neutrinos - invisible "ghost particles" which exist in great quantities but normally pass straight through Earth undetected Exploring the geometry of the dark Universe

Euclid of Alexandria is considered to be the 'father' of geometry. In his most famous work, 'Elements', he brought together the knowledge of mathematics available in his time, presented it in a consistent way and defined a strict method of proof that became the model for later mathematics. Many structures, theorems and proofs are therefore named after Euclid - and now also a space telescope. The ALMA digs deeper into the mystery of planet formation

An international research team used the Atacama Large Millimeter/submillimeter Array (ALMA) to observe disks around 19 protostars with a very high resolution to search for the earliest signs of planet formation. This survey was motivated by the recent findings that planet formation may be well-underway in the more-evolved proto-planetary disks, but until now there had been no systematic study to IceCube shows Milky Way galaxy is a neutrino desert

The Milky Way galaxy is an awe-inspiring feature of the night sky, dominating all wavelengths of light and viewable with the naked eye as a hazy band of stars stretching from horizon to horizon. Now, for the first time, the IceCube Neutrino Observatory has produced an image of the Milky Way using neutrinos - tiny, ghostlike astronomical messengers.

A European spacecraft is set to launch on a mission to help astronomers resolve an “embarrassing situation” in cosmology, although the launch itself is another kind of embarrassing situation for Europe.

The Mars Sample Return mission is starting to look expensive
Thursday, 29 June 2023 15:57 Write a comment
Getting to space is hard. It's even more hard to do new and interesting things in space. And when projects get hard, that usually means they cost more money. That is certainly the case for one of the most anticipated missions on NASA's current docket—the Mars Sample Return (MSR) mission. And it's not looking like it's going to get any easier anytime soon.
A recent report from Casey Dreier, the Planetary Society's Chief of Space Policy, looks at some of the challenges the mission faces. Arguably, the mission itself has already started, with Perseverance busily capturing, analyzing, and then dropping off samples to be returned to the laboratories on Earth. But three other main mission components still need to be completed for those samples ever to see the light of day (or the light of a sealed laboratory chamber) on Earth.
NASA is responsible for two of those components—the Sample Return Lander (SLR) and the Mars Ascent Vehicle (MAV). Each is appropriately named, as the SLR is designed to land, collect the samples that Perseverance has been collecting, and then return them to the MAV.

Virgin Galactic successfully commenced commercial spaceflights on Thursday, marking a major milestone for the company founded in 2004 by British billionaire Richard Branson.
Its inaugural customers were a three-member crew from the Italian Air Force and National Research Council of Italy, alongside a Virgin Galactic astronaut instructor occupying the fourth seat.
