  • How Much Are Asteroids Really Worth?

    How Much Are Asteroids Really Worth?
    Popular media love talking about asteroid mining using big numbers. Many articles talk about a mission to Psyche, the largest metallic asteroid in the asteroid belt, as visiting a body worth $10000000000000000000, assumedly because their authors like hitting the “0” key on their keyboards a lot. But how realistic is that valuation? And what does it actually mean? A paper funded by Astroforge, an asteroid mining start-up based in Huntington Beach, and written by a professor at the Col

    Euclid Could Find 170,000 Strong Gravitational Lenses
    Gravitational lensing is a concept where dark matter distorts space revealing its presence through its interaction with light. ESA’s Euclid mission is mapping out the gravitational lensing events to chart the large scale structure of the Universe. Euclid is also expected to discover in excess of 170,000 strong gravitational lensing features too. AI is expected to help achieve this goal but machine learning is still in its infancy so human beings are likely to have to confirm each lens cand
  • Uranus’s Wobbling Moons Could Point to Oceans Under the Ice

    Uranus’s Wobbling Moons Could Point to Oceans Under the Ice
    Subsurface oceans of liquid water are a common feature of the moon’s of Jupiter and Saturn. Researchers are exploring whether the icy moons of Uranus and Neptune might have them as well. Their new paper suggests future missions to the outer Solar System could measure the rotation of the moons and detect any wobbles pointing to liquid oceans. Less wobble means the moons is mostly solid but large wobbles can indicate ice floating on an ocean of liquid. Uranus is the 7th planet in the So

    Sombrerostelsel schittert in nieuwe James Webb opname
    Op een nieuwe midden-infraroodopname van de NASA/ESA/CSA James Webb Space Telescope is het Sombrero-sterrenstelsel te zien, ook bekend als Messier 104 (M104). De kenmerkende, gloeiende kern die te zien is op beelden met zichtbaar licht schittert niet en in plaats daarvan is een gladde binnenschijf te zien. De scherpe resolutie van Webb's MIRI (Mid-Infrarood Instrument) brengt ook details van de buitenste ring van het sterrenstelsel in beeld en geeft inzicht in hoe het stof, een essentiële b
