New Hubble images add to the dark matter puzzle

The images and our best computer models don't agree.

  • Scientists can detect the gravitational effects of invisible dark matter.
  • Dark matter causes visual distortions of what's behind it.
  • The greater the distortion, the greater the amount of dark matter. Maybe.

    The world’s largest space camera’s first test subject? Broccoli.

    Construction is nearly complete for a camera that will take 3,200-megapixel panoramas of the southern night sky.

  • The Vera C. Rubin Observatory in Chile is about to get the world's biggest camera for astronomy.
  • The images the camera takes contain billions of pixels.
  • It can capture objects 100 million times fainter than the human eye can see.

    Time: Do the past, present, and future exist all at once?

    Does time exist? Here's what the debate is all about.

    • Everything we do as living organisms is dependent, in some capacity, on time. The concept is so complex that scientists still argue whether it exists or if it is an illusion.
    • In this video, astrophysicist Michelle Thaller, science educator Bill Nye, author James Gleick, and neuroscientist Dean Buonomano discuss how the human brain perceives of the passage of time, the idea in theoretical physics of time as a fourth dimension, and the theory that space and time are interwoven.
    • Thaller illustrates Einstein's theory of relativity, Buonomano outlines eternalism, and all the experts touch on issues of perception, definition, and experience.

    Scientists discover first 'intermediate-mass' black hole in massive merger

    It's the largest black hole merger ever observed by scientists.

    • In 2019, scientists detected gravitational waves that were later determined to come from the merging of two so-called "intermediate-mass" black holes.
    • These black holes were thought to exist, but had never been directly observed.
    • The discovery sheds new light on how black holes form.
