- ESA and Vast sign new post-ISS cooperation agreement — European Space Agency
The European Space Agency signed a Memorandum of Understanding with Vast at the 77th International Astronautical Congress. The agreement builds on a 2024 MoU and four already-planned crewed missions to the International Space Station and Haven-1. It creates a framework for potential European astronaut flights aboard Haven Station, ESA hardware contributions, jointly defined research campaigns, and dedicated science accommodations after the International Space Station ends operations. ESA Director General Josef Aschbacher noted that the International Space Station has been one of the greatest examples of international cooperation in space. Director of Human and Robotic Exploration Daniel Neuenschwander said the cooperation helps Europe prepare for the post-ISS era. Vast CEO Max Haot said the company is designing Haven Station to ensure continued European access to low-Earth orbit.

A team from Diego Portales University identified Elias 2-24b as the youngest confirmed exoplanet to date. Researchers reanalyzed coronagraph observations from the European Southern Observatory’s Very Large Telescope and compared 2018 and 2020 data from the W.M. Keck Observatory in Hawaii. The planet appears as a gravitationally bound point of light inside a gap in the disk around the star Elias 2-24. The gap is thought to have been carved by the forming planet. Traditional transit methods miss such young worlds because they are still embedded in dense disks of gas and dust.

The Sharjah Space and Astronomy Hub ran a week-long program of lectures, planetarium shows, and interactive stations. Events included a talk on the hidden power of space exploration, a history of rockets traced through physical models, and stations where visitors designed mission patches. Director Prof. Hamid M.K. Al Naimiy said the hub uses interactive methods to nurture scientific curiosity among younger generations. Acting Planetarium Director Fatima Mohammed Al Khatri noted that the activities combine knowledge with experience to deepen passion for space. The program aligns with the United Nations-established World Space Week theme. Source: sharjah24.ae - Crew Dragon sets new U.S. record for fastest trip to station — Teslarati
Crew Dragon Grace docked at the Harmony module forward port seven hours and fifty-five minutes after liftoff from Cape Canaveral. NASA confirmed the flight as the fastest launch-to-docking of any U.S. spacecraft in International Space Station history. The previous U.S. record was held by an earlier Dragon cargo mission that took just over twelve hours. The rapid transit resulted from favorable orbital phasing rather than new hardware. The crew included NASA astronauts Jessica Watkins and Luke Delaney, Canadian Space Agency astronaut Joshua Kutryk, and Roscosmos cosmonaut Sergey Teteryatnikov.

The ESA-CAS SMILE mission recorded a full auroral oval visible even during daylight hours. The time-lapse video covers roughly one hour in late July and shows the oval’s turbulent variability in ultraviolet light. Stars appear to drift across the frame because the spacecraft’s camera view shifts during its orbit. One goal of SMILE is to study how the solar wind interacts with Earth’s magnetosphere to improve protection of astronauts, spacecraft, and power grids.

The Operational Land Imager on Landsat 9 captured rivers carrying colored dissolved organic matter into Hannah and Rupert bays on September 27, 2026. The brown staining comes from tannins and lignins leached from decaying vegetation in the boreal forests of northern Quebec and Ontario. Postglacial rebound has created shallow, sloping mudflats where river sediment mixes with incoming tidal water. Green dendritic patterns onshore reflect differences in moisture and vegetation.

Researchers modeled how a neutron inside the ergosphere of Sagittarius A* could decay into a proton, electron, and neutrino while extracting rotational energy. The ergosphere is the region where frame-dragging is so strong that nothing can remain stationary. The process, first proposed by Roger Penrose in 1969, allows a particle to escape with more energy than it entered by leaving negative energy behind. Magnetic-field interactions could make the mechanism far more efficient than the basic version. The study appears on the arXiv preprint server.

RCSI University’s Dr Ronan Lordan reviewed how a ninety-minute orbital period creates sixteen sunrises and sunsets per day, breaking the usual light-dark cues for the circadian clock. Two biological systems normally align sleep pressure and circadian timing, but spaceflight can separate them. Astronauts receive eight and a half hours of scheduled sleep opportunity, yet the mismatch can leave them tired without being biologically ready for sleep. Tailored lighting, exercise timing, and meal scheduling are used to mitigate the effects.

After six months at “Lac de Charmes” beyond Jezero crater’s western rim, Perseverance encountered a field of light-toned boulders. Data indicate many are gabbro formed by slow cooling of magma deep in the crust. The rover is investigating a possible bedrock outcrop of angular rock fragments that may be the source of the scattered boulders. The team is using arm-mounted instruments at the “Idubi” site to analyze composition and texture.

New analysis of Hubble observations suggests a planet candidate is accreting onto a white dwarf, implying a second-generation planetary system. The work revives an earlier cold case by showing material from a disrupted body falling onto the stellar remnant. Such systems would form after the star’s red-giant phase destroyed any original planets.

The study presents evidence that a planet formed after the host star became a white dwarf is now losing material to the star. The detection relies on spectroscopic signatures of ongoing accretion. This would be the first known example of a planet forming in the debris disk of a stellar remnant.

The report summarizes the Hubble and Nature findings on a planet candidate orbiting a white dwarf. It notes that the system would represent the first detected case of planet formation after a star’s death.

Cosmic Spotlight
The Perseverance team is now examining whether light-toned gabbro boulders eroded from a breccia outcrop at “Idubi.” If confirmed, the finding would show how deep-crustal material reached the surface through impact or tectonic processes. The rover’s arm instruments are collecting composition and texture data that could distinguish between formation scenarios. Such rocks are rare on the dark basaltic surface of Mars and may preserve records of the planet’s early magmatic history. The next steps involve targeted abrasion and close-up imaging before the rover continues its traverse.
Cosmic Deep Dive: Frame-Dragging Around Rotating Black Holes
A teaspoon of material near a spinning supermassive black hole can be forced to circle at nearly the speed of light simply because space itself is being twisted. The ergosphere around Sagittarius A* stretches roughly one astronomical unit across, yet within that zone the rotational drag is so complete that even a photon cannot stand still relative to a distant observer. A neutron drifting into this region can split, sending one fragment inward on a path that carries negative energy while the other escapes with a net gain. The entire process can repeat on timescales measured in milliseconds, turning the black hole’s spin into a reservoir that could power jets or flares. No one has yet detected the unique spectral signature that would confirm the Penrose mechanism is operating at the galactic center.
