On September 2, 2023, a coronal mass ejection (CME) launched by our sun hit Comet Nishimura (C/2023 P1), causing a disconnection event and stripping its tail. This encounter occurred while the comet was located about halfway between the orbits of Mercury and Venus.
Cryovolcanic comet 29P/Schwassmann-Wachmann suddenly brightened by more than 4 magnitudes on November 22, 2022, signaling a new significant eruption/outburst was underway. After the eruption, cryomagmatic debris started expanding in a shell shaped like Pac-Man.
An international team of scientists reporting in The Astronomical Journal discovered a large Apollo-type near-Earth object (NEO) hiding in the Sun’s glare.
A bright Kreutz sungrazing comet appeared in ESA/NASA SOHO C3 coronagraph imagery on July 11 and entered the C2 field of view on July 13, just before it faced its total destruction.
Comet 2017 K2 (PanSTARRS) – dubbed ‘The Record-Breaker’ – will make its close approach to Earth on July 14, 2022, and then reach perihelion (the closest point to the Sun) on December 19, close to the orbit of Mars. The comet is record-breaking because it was already becoming active when it was discovered in 2017 under the feeble glow of the distant Sun.
On May 15, 2022, Earth is expected to pass through a debris field created by asteroid 2006 GY2, potentially creating a meteor outburst.
A large near-Earth asteroid designated 1994 PC1 will fly past Earth at a distance of 5.5 LD / 0.01325 AU (1.98 million km / 1.23 million miles) on January 18, 2022. This is the second-closest approach of this object to Earth since 1933. 1994 PC1 is an Apollo-class…
This bright North Taurid fireball overflew the Mediterranean Sea at 22:52 UTC on November 7, 2021. It was produced by a fragment from Comet Encke that hit the atmosphere at about 111 000 km/h (68 970 mph). The fireball began at an altitude of about 101 km (62 mph)…
Comet Bernardinelli-Bernstein (C/2014 UN271) — the largest comet ever discovered — is heading towards our solar system and forecast to make its closest approach in 2031 at 10.1 AU or slightly farther than Saturn. The current estimate suggests its nucleus is…
SETI Institute researchers are reporting that they can now detect showers from the debris in the path of comets that pass close to Earth orbit and are known to return as infrequent as once every 4 000 years. "This creates a situational awareness for potentially…
