In 2003, a success story of astrophysics began on La Palma: 20 years ago in October, the first MAGIC telescope was inaugurated on the Canary Island, a huge instrument with a mirror diameter of 17 meters. Five years later, the twin MAGIC II telescope followed. The two Cherenkov telescopes measure…

The MAGIC telescopes on La Palma are on the hunt for dark matter. For 233 observational hours, their cameras were pointed at the center of the Milky Way, our home galaxy. Scientists suspect a particularly large accumulation of non-luminous, invisible matter there. However, the search yielded no…

Julia Summerer has just graduated from high school. She is currently doing an internship at the Max Planck Institute for Physics, more precisely with the "MAGIC" working group. The scientists in this group are working on two large telescopes of an international research collaboration on the Canary…

The MAGIC telescopes have observed the nova RS Ophiuchi shining brightly in gamma rays at extremely high energy. The Gamma rays emanate from protons that are accelerated to very high energies in the shock front following the explosion. This suggests that novae are also a source of the ubiquitous…

Messier M87 is 55 million light years away from Earth. As is the case for probably all galaxies, there is a huge black hole in its center. In 2017, a host of telescopes observed the object over the entire energy spectrum. The spectacular result of this extensive observation campaign was the famous…

In 2019, the MAGIC telescopes detected the first Gamma Ray Burst at very high energies. This was the most intense gamma-radiation ever obtained from such a cosmic object. But the GRB data have more to offer: with further analyses, the MAGIC scientists could now confirm that the speed of light is…

The gamma-ray burst recorded by the two MAGIC telescopes on 14 January 2019 was spectacular: Never before have astrophysicists captured a gamma-ray burst with such high energy – hundreds of billions times more intense than that of visible light. MAGIC did not capture the gamma-ray burst until the…

For the first time, astrophysicists have localized the source of a high energy cosmic neutrino originating outside the Milky Way. It is highly likely that the neutrino comes from a blazar, an active black hole at the center of a distant galaxy in the Orion constellation. How did the scientists reach…

15 years ago, the first MAGIC telescope was inaugurated on La Palma in the Canary Islands. In 2009, it was followed by a second telescope of a similar type. Both instruments study cosmic objects that emit high-energy gamma rays, such as supernovae or massive, active black holes in the center of…

What gives the particles of cosmic radiation, which permeate the universe, their high energy? It is suspected that supernova remains might act as naturally occurring particle accelerators. Cassiopeia A is one of a handful of such objects in our galaxy and has therefore long been regarded as a…
