The first time that an "exploding pulsar" was a slow-pulsating transient pulsar

The University of Southampton, Great Britain, discovered that a unique "exploding pulsar" - a neutron star that "pulls" matter from a companion star - may also be the slowest transient pulsar known to science. Transient pulsars are a rare class of neutron stars that perform transitions from x-ray to radio pulsations and back for several years.

The helium for the first time on a planet outside of our solar system

The international teams of astronomers have detected helium in the atmosphere of WASP-107b. It is the first time that this chemical element has been detected in the atmosphere of an exoplanet.

The astronomers, led by Jessica Spake, of the University of Exeter in the United Kingdom, used

The rings of Saturn crossed an impossible way

At first momentary look, the rings of Saturn seem to cross each other in an impossible way. In fact, what this view of the Cassini international ship shows are the rings that pass in front of the planet, on which they project their shadow. And because the rings like those of the A ring and the Cassini division,
