A camera captured what appears to be a meteor crossing the night sky over Viña del Mar, Valparaíso, in the early hours of Monday, February 10.

The director of the Hellenic National Meteorological Service (EMY), Theodoros Kolydas, explained that the mysterious morning glow observed by some in the Attic sky on early Monday was caused by a meteor entering Earth's atmosphere.

A video captured by a camera mounted on a meteorological station in Acharnes shows a sudden flash of light that does not appear to originate from cloud formations.

Kolydas confirmed that the phenomenon was indeed a meteor, with its glow visible across central Greece.

"For an observer on Earth, meteors that enter the atmosphere in the early morning hours travel at higher speeds and are more difficult to spot, whereas those appearing in the early evening move more slowly," he noted.

An international team of astronomers has investigated a newly detected Type II supernova designated SN 2024jlf. The new study, detailed in a paper published Jan. 30 on the arXiv pre-print server, yields important information regarding the evolution of this supernova and the nature of its progenitor.

Type II supernovae (SNe) are the results of rapid collapse and violent explosion of massive stars (with masses above 8.0 solar masses). They are distinguished from other SNe by the presence of hydrogen in their spectra.

Based on the shape of their light curves, they are usually divided into Type IIL and Type IIP. Type IIL SNe show a steady (linear) decline after the explosion, while Type IIP exhibit a period of slower decline (a plateau) that is followed by a normal decay.

SN 2024jlf was first spotted on May 28, 2024 using the Zwicky Transient Facility (ZTF), with a brightness of 15.88 mag. The supernova occurred in NGC 5690 — an edge-on spiral galaxy at a redshift of 0.0058.

Subsequent observations of SN 2024jlf after its discovery have revealed that its spectrum shows a blue continuum with weak flash features, indicating a young core-collapse supernova of Type II. A search for the progenitor of SN 2024jlf has also been conducted. However, no source has been identified in the location of this supernova.

A fireball was spotted streaking across the sky above Guadalajara in Jalisco, Mexico, on the morning of Wednesday, January 29.

Footage from Webcams de Mexico shows the bright object shooting over Jalisco's state capital.

According to the American Meteor Society (AMS), meteors were expected to be visible from January 25 to January 31.

People in the South Island have witnessed a fireball break through the atmosphere near Wānaka with a loud sonic boom.

The meteoroid became a fireball and raced above Queenstown about 11pm on Friday, before burning out over Southland.

Fireballs Aotearoa, a group interested in meteorites, said a sonic boom was widely reported as the object came in overhead.

Although most of its mass burned up in the fireball stage, it was believed a small meteorite may have landed in a remote portion of the Eyre Mountains in northern Southland.

Fireballs Aotearoa are on the hunt for it and believe it may have landed in the Eyre Mountains in Southland.

A very bright fireball exploded over the skies of the Río de la Plata area at around 01:15 UTC on February 2, 2025, creating a spectacular display for people of both Uruguay and Argentina.

A very bright fireball exploded over the Rio de La Plata, Argentina at approximately 01:15 UTC on February 2 (22:15 local time on February 1). The Rio de La Plata area, situated south of Uruguay, shares a coastline with Argentina.

Social media reports indicate that the fireball had a green trail, which suggests the presence of magnesium.

The discovery marks only the second time that an asteroid's impact risk has reached greater than a 1% chance.
Astronomers — professional and amateur alike — have turned their attention to an asteroid with a slight chance of impacting Earth in 2032, based on current observations. While the possibility is slim, and more observations are needed, the object itself might be large enough to devastate a city, motivating follow-up observations as well as archival searches for pre-discovery observations.

The asteroid, designated 2024 YR4, was first noticed on December 27, 2024, by the Asteroid Terrestrial-impact Last Alert System (ATLAS); searches quickly revealed that ATLAS had already imaged it two days earlier. Then, as observations accumulated, astronomers could roughly determine its orbit. That's when the realization dawned: The object has some chance of striking Earth.

On Monday, January 27th, NASA's Sentry impact-tracking system officially raised the asteroid to a level 3 on the Torino scale. This is only the second time that an asteroid has merited a rating greater than 2 on the 10-point Torino scale, created in 1999 to convey the risk of an impact. At this level, an object has more than 1% chance of striking Earth.

Only one other object, asteroid 99942 Apophis, discovered in 2004, has ever reached that high on the scale. That asteroid peaked at 4, with a possibility of impact in 2029. But additional observations soon ruled that out, sending it back to a Torino rating of 0 — meaning no possible impact within the next century.

The chance of impact for 2024 YR4 is still slim: NASA's Jet Propulsion Laboratory estimates 1.2%. But if it does happen, German astronomer Daniel Bamberger (Northolt Branch Observatories) has used observations in hand to constrain the possible impact in time and location: The impact would take place on December 22, 2032, somewhere along a long line that extends from the Pacific Ocean off the coast of Mexico, through Ecuador and northern South America, across the Atlantic, through central Africa (from Kenya to Somalia), and then across to northern India.

The possible impact track covers big stretches of ocean as well as populated areas and some large cities. "I'd be really excited to see an impact," Bamberger says, "but I don't want it to be this one. Something over Antarctica, please!"
