On April 28, a supermagnetized stellar remnant known as a magnetar blasted out a simultaneous mix of X-ray and radio signals never observed before. The flare-up included the first fast radio burst (FRB) ever seen from within our Milky Way galaxy and shows that magnetars can produce these mysterious and powerful radio blasts previously only seen in other galaxies.

Astronomers have used NASA's telescopes, including the Neil Gehrels Swift observatory, to observe one of the largest black hole known, named OJ 287. OJ287 is a blazar hosting a black hole with the mass 18 billion times that of the Sun, and orbited by a smaller companion black hole, "only'' 150 million times more massive than the Sun. The pair of black holes has been monitored since late 2015 with NASA's Swift satellite and in a recently published paper a team of astronomers report a flash of ultraviolet and X-ray radiation. These observations provides a unique laboratory to study black hole feeding, jet formation, and general relativity.

On Nov. 20, 2004, NASA's Neil Gehrels Swift Observatory took to the skies aboard a Delta 7320 rocket and entered orbit around Earth. The satellite was on the hunt to uncover the mystery of gamma-ray bursts, the universe's most powerful explosions.

For the first time, NASA's Neil Gehrels Swift Observatory tracked water loss from an interstellar comet as it approached and rounded the Sun. The object, 2I/Borisov, traveled through the solar system in late 2019.
