Despite decades of searching, scientists still haven’t found the elusive substance that holds galaxies together: dark matter.

The project is named for Caltech astronomer Fritz Zwicky. In the 1930s, Zwicky began hunting cosmic explosions with a small telescope from the frigid heights of the Palomar Mountain near San Diego.

In 1933, the Bulgarian-born astronomer Fritz Zwicky, working in the U.S., ... For this discovery, three scientists were awarded the 2011 Nobel Prize in Physics.

But the so-called "tired light theory" that originated in 1929 with Swiss astronomer Fritz Zwicky offered an alternative explanation: Perhaps the redshift we see isn't due to galaxies moving away ...

In the 1930s, Swiss astronomer Fritz Zwicky observed that the velocities of galaxies in the Coma Cluster were too high to be maintained solely by the gravitational pull of luminous matter. He ...

If you have such an instrument, you’ll find Zwicky’s Necklace a bit more than 31/2° southeast of magnitude 4.3 Tau (τ) Virginis. This object was discovered more than four decades ago, but ...

IT HAS been almost a century since Fritz Zwicky first hypothesised the existence of dunkle materie – which translates to “dark matter” in English. In 1933, looking at observations of galaxy ...

The team has probed gas outflows in I Zwicky 1, a close-by quasar, to map its system of clouds being blown away at tens to thousands of kilometers per second. Their findings are published in the ...

The Zwicky Transient Facility has reached an incredible milestone, classifying over 10,000 supernovas, cosmic explosions that mark the death of massive stars.
