James Webb telescope

Just saw another video that blew my mind

This is what hubble just did.

The Andromeda galaxy. It took 600+ photos. And over 10 years. (Because you have to wait to be lined up to take the photo) from 2015 to 2025

NGR will take an afternoon to do the same thing.

Roman, Hubble, and Webb are now in space – each seeing the universe in a different way.

Hubble sees sharply. Webb sees deeply. Roman sees widely.

NASA’s Nancy Grace Roman Space Telescope launched from Florida on August 30 aboard a SpaceX Falcon Heavy rocket.

The $4 billion observatory is now traveling approximately 1 million miles (1.6 million kilometers) to the second Sun-Earth Lagrange point, known as L2. It will spend about three months reaching its destination and completing tests before NASA releases its first images, expected by early 2027.

Roman’s specialty is seeing the bigger picture.

Its 7.9-foot (2.4-meter) mirror is the same size as Hubble’s, but its field of view is at least 100 times wider. A single Roman image can capture roughly the same area as 100 Hubble images while maintaining similar sharpness.

That will allow Roman to survey the universe up to 1,000 times faster than Hubble. It will study more than a billion galaxies, investigate dark matter and dark energy, and search for more than 1,000 planets beyond our solar system.

Hubble, meanwhile, remains astronomy’s precision observer.

Orbiting roughly 320 miles (515 kilometers) above Earth, it studies the universe in ultraviolet, visible, and near-infrared light. Since 1990, Hubble has captured detailed views of planets, stars, nebulae, and distant galaxies, helping scientists measure the age and expansion of the universe.

Webb looks deeper.

Located near L2, the James Webb Space Telescope uses a 21-foot (6.5-meter) mirror and powerful infrared instruments to examine some of the earliest galaxies, peer through clouds of cosmic dust, and study the atmospheres of distant planets.

Roman will find enormous numbers of objects across wide areas of the sky. Webb can then examine selected targets in extraordinary detail, while Hubble adds observations at wavelengths the other two cannot fully see.

that’s insane and wonderful.

Don’t get too excited – but the world’s largest detector spotted a single weird particle.

The LUX-ZEPLIN experiment, the world’s largest detector built to search for dark matter, observed a single high-energy interaction inside its tank of ultrapure liquid xenon.

Researchers investigated whether it could have been produced by a stray neutron, gamma ray, detector malfunction or another known source. So far, none of those explanations fits convincingly.

That raises an extraordinary possibility: the detector may have recorded a particle of dark matter.

Dark matter cannot be seen because it does not emit, reflect or absorb light. Scientists infer its existence from its gravitational influence on galaxies and estimate that it constitutes roughly 85% of all matter in the universe.

LUX-ZEPLIN attempts to detect it directly by watching for an invisible particle striking the nucleus of a xenon atom and causing it to recoil.

The unexplained event deposited approximately 248 kiloelectron volts of energy—far more than expected from the conventional dark-matter particles the experiment was designed primarily to find.

If dark matter caused it, the particle may interact with ordinary matter in a more complicated way than standard theories predict. It could possess an internal structure or interact more strongly during higher-energy collisions.

But one event is nowhere near enough to declare a discovery.

Researchers estimate there is approximately a one-in-200 chance that the signal is a statistical fluctuation. Particle physicists generally require odds of roughly one in 3.5 million before announcing a discovery.

The team has already collected about three times more data than was included in this analysis. Other detectors in Italy and China can also search independently for similar high-energy events.

If more signals appear, this event could become the first glimpse of the invisible matter holding galaxies together.

I won’t get too excited, though I am interested because I took the under on dark matter in predictive markets. You’d expect that from a founding member of the Dark Matter Untruthers.

BepiColombo, the joint ESA and JAXA mission to Mercury, reached a critical milestone on September 3 when it separated its Mercury Transfer Module — the propulsion unit that powered the spacecraft through 8 years of interplanetary travel, including nine planetary flybys and six close passes of Mercury itself. What remains is a historic first: two orbiters — ESA’s Mercury Planetary Orbiter (MPO) and JAXA’s Mio — traveling to the same planet together. “For the first time, we’ll have a single mission with two orbiters going around the same planet,” said Professor Geraint Jones, BepiColombo’s Lead Project Scientist. MPO will map Mercury’s surface, interior, and tenuous atmosphere using X-ray imaging, while Mio will study the planet’s magnetic environment and solar wind interactions. The orbiters will enter Mercury’s orbit on November 21, with science operations beginning on April 6, 2027. Getting to Mercury is notoriously difficult: anything launched from Earth carries our planet’s orbital velocity, making it necessary to lose enormous amounts of energy to fall inward toward the Sun. BepiColombo solved this through a series of gravity assists spanning Earth, Venus, and Mercury over nearly a decade. The mission took 15 years to build its instruments alone.

Floating data center uses ocean heat to power 32,000 homes and supply fresh water to 150,000 people.

Called Kraaken, the vessel would combine computing, electricity generation, and seawater desalination in one offshore platform.

Developer Optimal Transit estimates it could send 40 megawatts of electricity ashore and produce 7.9 million gallons (30 million liters) of fresh water daily, while reserving 60 megawatts for AI computing.

The design would draw energy from the temperature difference between warm surface seawater and cold water deep below.

Warm water would heat a fluid such as ammonia until it vaporizes. That vapor would drive a turbine to generate electricity, before cold seawater turns it back into liquid so the cycle can repeat.

Heat from the computer servers would provide an additional boost.

The same thermal system would also help remove salt from seawater. Inside a low-pressure chamber, water can boil at much lower temperatures than usual. The vapor leaves its salt behind and is cooled back into fresh water.

Electricity, water, and data would reach shore through connections designed to detach. The company says the vessel could move away before major storms or relocate to communities needing emergency support.

But Kraaken is still a proposal, and its promised performance has not been demonstrated at this scale.

Ocean thermal power requires moving enormous volumes of seawater. Engineers would also need to show how the deep-water intake could safely disconnect and how much energy the pumps, desalination equipment, and ship itself would consume.

The concept brings several established technologies together. The major test is whether they can deliver the promised power, water, and computing aboard one movable vessel.

Ocean thermal….very cool.

This is the kind of s*** I’ve been talking about that makes everybody go cross-eyed when I say the carrying capacity of this planet is probably closer to 50 billion people than it is what it is now. We have done almost nothing with the oceans and the potential there is so incredibly vast it’s hard to come up with a finite limit to it.

Now add in pushing all the data computation and solar generation into space. Now start building ocean habitats and space habitats and space elevators and other funky stuff that we haven’t really touched on yet. Not that we’re going to get to 50 billion people because young people won’t f*** and we’re going to have three robots for every person and money will be irrelevant, or at least those are some outcomes that don’t seem as easily written off at face value as they were not too long ago

OK, something else that is cool…

A massive electric aircraft has completed its maiden flight while reportedly using about five dollars in electricity.

Such a low energy cost could change how aviation companies approach short trips, cargo transport, and regional travel.

Electric aircraft promise quieter flights and fewer direct emissions than planes powered by conventional jet fuel.

Battery weight, charging time, range, and certification still present major hurdles for developers.

Yet a successful first flight gives engineers valuable data for further testing and improvement.

Commercial adoption may take years, but each working aircraft brings electric aviation closer to daily use.

why can’t it just use the wind turbines on the wings to generate electricity? are they dumb?

Well, how are they going to generate chemtrails? :eyes:
