The tau Herculids from comet 73P/Schwassman-Wachmann which began to fragment in 1995 may make an appearance on the night of May 30-31.
Comets are remnants from the early days of the solar system, billions of years ago. Primarily made of ice and dust, these "dirty snowballs" orbit the sun and in habit the Oort cloud, an area in the outskirts of the solar system beyond Pluto. As comets approach the inner solar system, solar wind from the sun can sweep dust back into a long tail. When these comets are close enough to Earth, they can appear as dazzling objects in the night sky. Space probes from Earth have visited several comets to learn more about their composition.

May offers an unusual skywatching bounty: the possibility of two major celestial highlights occurring within the span of a single month.
Thirty alien comets have been spotted transiting the young star Beta Pictoris, their long tails lighting up the skies of the fledgling planets forming there.
A gigantic comet is actually the largest ever seen, new observations by the Hubble Space Telescope confirm.
When comets first appear near Earth, their bright tails of ionized gas stun observers, but on every subsequent return, they become dimmer.
Recently discovered comet Pan-STARRS is heading towards the sun in late April, but will we be able to see it?
Observations from the Hayabusa2 mission have astronomers questioning the true origin of asteroid Ryugu, a new study shows.
While planets and some moons are almost perfectly spherical, the smaller bits of the solar system, such as asteroids and comets, come in all different shapes. But why is that?
The Bernardinelli-Bernstein comet is officially the largest ever observed, according to new measurements.
Reference Hale-Bopp was an unusually bright comet that flew close to Earth in 1997. Tragically, Hale-Bopp also influenced the Heaven's Gate cult's mass suicide.
Researchers think that comet fragments may have exploded over Ohio 1,600 years ago, triggering a violent airburst and starting wildfires that devastated the Hopewell people's crops and the landscape.
As Comet Leonard bid farewell to Earth and flew past Venus, a sun-studying spacecraft flew through the comet's long tail, giving humans a new perspective on the icy wanderer.
Adam McKay, creator of Netflix's popular satire-comedy movie "Don't Look Up," and climate scientist Kate Marvel talk why the world needs more films like the comet metaphor movie.
Comet Leonard shines brightly in images captured by a small Chinese satellite on the backdrop of aurora and passing meteors.
Comets heat up very quickly as they approach the sun, causing the icy bodies to glow green, but never in the tails trailing behind them. A new study may finally reveal why.
