Does Dark Matter Exist?

The dark matter problem started with the famous Swiss physicist Fritz Zwicky in 1933, when he studied galaxy motion in the giant Coma group. What he perceived was astonishing. Each member moved so quickly, it should have no problem escaping the gravitational glue of the entire assembly. Zwicky realized that this galaxy cluster — and all others, it soon turned out — shouldn't even exist. Yet there they were.

  • The NASA/ESA Hubble Space Telescope reveals the intricate, detailed beauty of Jupiter’s clouds in this new image taken on 27 June 2019 by Hubble’s Wide Field Camera 3, when the planet was 644 million kilometres from Earth — its closest distance this year. The image features the planet’s trademark Great Red Spot and a more intense colour palette in the clouds swirling in the planet’s turbulent atmosphere than seen in previous years. The observations of Jupiter form part of the Outer Planet Atmospheres Legacy (OPAL) programme.

    Europa
    Bob Berman
    Jupiter passed behind the Sun a week ago, so it’s still lost in the solar glare. By next month, early risers will start seeing brilliant Jupiter in the east before dawn, as a morning star. But when we think of that giant planet, people who care about astronomy think of its strange moon Europa, which is probably the likeliest place for life in the known universe.
  • This image from the NASA/ESA Hubble Space Telescope captures the spiral galaxy NGC 105, which lies roughly 215 million light-years away in the constellation Pisces. While it looks like NGC 105 is plunging edge-on into a collision with a neighbouring galaxy, this is just the result of the chance alignment of the two objects in the night sky. NGC 105’s elongated neighbour is actually far more distant and remains relatively unknown to astronomers. These misleading conjunctions occur frequently in astronomy — for example, the stars in constellations are at vastly different distances from Earth, and only appear to form patterns thanks to the chance alignment of their component stars. The Wide Field Camera 3 observations in this image are from a vast collection of Hubble measurements examining nearby galaxies which contain two fascinating astronomical phenomena — Cepheid variables and cataclysmic supernova explosions. Whilst these two phenomena may appear to be unrelated — one is a peculiar class of pulsating stars and the other is the explosion caused by the catastrophic final throes of a massive star’s life — they are both used by astronomers for a very particular purpose: measuring the vast distances to astronomical objects. Both Cepheids and supernovae have very predictable luminosities, meaning that astronomers can tell precisely how bright they are. By measuring how bright they appear when observed from Earth, these “standard candles” can provide reliable distance measurements. NGC 105 contains both supernovae and Cepheid variables, giving astronomers a valuable opportunity to calibrate the two distance measurement techniques against one another. Astronomers recently carefully analysed the distances to a sample of galaxies including NGC 105 to measure how fast the Universe is expanding — a value known as the Hubble constant. Their results don’t agree with the predictions of the most widely-accepted cosmological model, and their analysis shows tha

    Weird White Dwarfs
    Bob Berman
    White dwarf stars happen to be some of the strangest stars in our galaxy. These nights they can appear during the next clear evening at nightfall orbiting our closest celestial neighbors: the Dog Star Sirius and Procyon, the main star of the Canis Minor constellation.
