Cosmic Slowpoke: The Neutron Star That Defies Speed Limits

A newly discovered neutron star, found by an international team using the ASKAP radio telescope, spins every 54 minutes, making it the slowest of its kind.

This discovery could alter scientific theories about neutron stars and white dwarfs, emphasizing the need for more research to understand their emission properties and evolutionary paths.

Astronomers have detected what they believe to be a neutron star spinning at an unprecedentedly slow rate — slower than any of the more than 3,000 radio-emitting neutron stars measured to date.

TIMELAPSE of Future Space Stations (Sci-fi Documentary)

What happens when humanity begins living in space, building larger space stations, and creating a purely space based economy. Space drones will deliver goods between stations, farming stations will grow food, and space hotels will host celestial events and viewing parties for eclipses and welcoming parties for spaceships returning from Mars.

This sci-fi documentary takes a look at the future of space stations and space technology, starting with the retiring of the International Space Station, and ending with the construction of the largest rotating ring world space station, with its own atmosphere and lakes that evaporate creating clouds and rain.

Other topics in this video include: stealth based technology and metamaterials, the future of Starship Mark 2, cryo refuelling in space, Moon space stations, the Mars Colony, asteroid mining station, future space telescope stations, design concepts, and cryo sleep.

Something in space has been pulsing every 22 minutes for at least 35 years

Researchers reported the discovery of a new cosmic conundrum. The new object, GPM J1839-10, operates similarly to a pulsar, emitting frequent bursts of radio radiation. However, the physics that drives pulsars dictates that they would cease generating if they slowed too much, and practically every pulsar we know of blinks at least once every minute.

GPM J1839-10 has a pulse interval of 22 minutes. We don’t know what type of physics or things can power it.

Space mission that maps forests in 3D makes an early comeback

Call it the force’s doing, but it has been surprises galore for the GEDI mission.

In early 2023, the lidar mission that maps the Earth’s forests in 3D was to be burned up in the atmosphere to make way for another unrelated mission on the International Space Station. A last-minute decision by NASA saved its life and put it on hiatus until October 2024. Earlier this year, another surprise revealed itself: the mission that replaced GEDI was done with its work, effectively allowing GEDI to get back to work six months earlier than expected.

That’s how, in April, a robotic arm ended up moving the GEDI mission (short for Global Ecosystem Dynamics Investigation and pronounced “Jedi” like in the Star Wars films) from storage on the ISS to its original location, from where it now continues to gather crucial data on aboveground biomass on Earth.

TeraNet Unleashes 1000x Faster Space Communications With Laser Technology

The University of Western Australia’s ‘TeraNet’, a network of optical ground stations specializing in high-speed space communications, has successfully received laser signals from a German satellite in low Earth orbit. This breakthrough paves the way for a 1,000-fold increase in communication bandwidth between space and Earth.

TeraNet’s laser communication test with OSIRISv1 marks a step towards replacing outdated radio systems with high-speed lasers for space communications in Western Australia. With funding from Australian governments, the network aims to support diverse missions, enhancing data transfer capabilities across multiple sectors.
