The American Meteor Society website shared a video on their channel showing a fireball streaking across the skies of Michigan and Ohio on Sunday, January 19, 2025, around 01:31 UT.
Though, Meteor Society noted that the video might not actually depict a fireball event, leaving some viewers curious about the meaning behind this statement.
At the moment the fireball appears on camera, a strange object seems to materialize above it, expanding in size and partially obscuring the fireball before gradually fading out as the fireball continues its path through the sky.
This phenomenon has sparked varied interpretations. Some suggest it might indicate alien intervention, while others offer a more plausible explanation: the "object" is likely a water droplet on the camera lens, creating the illusion of interaction with the fireball.
However, since the Meteor Society suggested that it might not actually depict a fireball event, we might question whether it was truly a fireball, a meteor, including a water droplet, or something entirely different.

January’s Night Sky Notes: The Red Planet
by Kat Troche of the Astronomical Society of the Pacific
Have you looked up at the night sky this season and noticed a bright object sporting a reddish hue to the left of Orion? This is none other than the planet Mars! January will be an excellent opportunity to spot this planet and some of its details with a medium-sized telescope. Be sure to catch these three events this month.
Martian Retrograde
Mars entered retrograde (or backward movement relative to its usual direction) on December 7, 2024, and will continue throughout January into February 23, 2025. You can track the planet’s progress by sketching or photographing Mars’ position relative to nearby stars. Be consistent with your observations, taking them every few nights or so as the weather permits. You can use free software like Stellarium or Stellarium Web (the browser version) to help you navigate the night as Mars treks around the sky. You can find Mars above the eastern horizon after 8:00 PM local time.
This mid-January chart shows the path of Mars from September 2024 to June 2025 as it enters and then exits in retrograde motion. Mars appears to change its direction of motion in the sky because Earth is passing the slower-moving Mars in its orbit. Stellarium Hide and Seek
On the night of January 13th, you can watch Mars ‘disappear’ behind the Moon during an occultation. An occultation is when one celestial object passes directly in front of another, hiding the background object from view. This can happen with planets and stars in our night sky, depending on the orbit of an object and where you are on Earth, similar to eclipses.
A simulated view of the Moon as Mars begins its occultation on January 13, 2025. Stellarium Depending on where you are within the contiguous United States, you can watch this event with the naked eye, binoculars, or a small telescope. The occultation will happen for over an hour in some parts of the US. You can use websites like Stellarium Web or the Astronomical League’s ‘Moon Occults Mars’ chart to calculate the best time to see this event.
Closer and Closer
As you observe Mars this month to track its retrograde movement, you will notice that it will increase in brightness. This is because Mars will reach opposition by the evening of January 16th. Opposition happens when a planet is directly opposite the Sun, as seen from Earth. You don’t need to be in any specific city to observe this event; you only need clear skies to observe that it gets brighter. It’s also when Mars is closest to Earth, so you’ll see more details in a telescope.

The mosaic is composed of 102 Viking Orbiter images of Mars. NASA/JPL-Caltech Mars has fascinated humanity for centuries, with its earliest recorded observations dating back to the Bronze Age. By the 17th century, astronomers were able to identify features of the Martian surface, such as its ice caps and darker regions. Since the 1960s, exploration of the Red Planet has intensified with robotic missions from various space organizations. Currently, NASA has five active missions, including rovers and orbiters, with the future focused on human exploration and habitation. Mars will always fill us with a sense of wonder and adventure as we reach for its soil through initiatives such as the Moon to Mars Architecture and the Mars Sample Return campaign.

NASA’s Night Sky Network is one of the most successful and longstanding grassroots initiatives for public engagement in astronomy education. Started in 2004 with the PlanetQuest program out of the Jet Propulsion Laboratory and currently supported by NASA’s Science Activation, the Night Sky Network (NSN) plays a critical role in fostering science literacy through astronomy. By connecting NASA science and missions to support amateur astronomy clubs, NSN leverages the expertise and enthusiasm of club members, who bring this knowledge to schools, museums, observatories, and other organizations, bridging the gap between NASA science and the public. Now in its 20th year, NSN supports over 400 astronomy clubs dedicated to bringing the wonder of the night sky to their communities across the US, connecting with 7.4 million people across the United States and its territories since its inception.

It all started with an idea – astronomy clubs already do great outreach, and club members know a lot of astronomy (shown definitively by founder Marni Berendsen’s research), and they love to talk with the public – how could NASA support these astronomy clubs in sharing current research and ideas using informal activities designed for use in the places that amateur astronomers do outreach. Thanks to funding through NASA JPL’s PlanetQuest public engagement program, the Night Sky Network was born in 2004, with more than 100 clubs joining the first year.

Connecting what we do with our missions to the sense of wonder that comes when you look up at the stars and the planets is one of our long-term objectives. We have a strong commitment to inspiring the next generation of explorers. Lending support to the energy that the amateur astronomy community brings to students and the public will allow NASA to reach many more people.”
Taking off like a rocket, Night Sky Network had over 100 clubs registered on their website within the first year.
The Toolkits
Outreach Toolkits were developed to assist clubs with their endeavors. These kits included educational materials, hands-on activities, and guides to explaining topics in an accessible way. So far, 13 toolkits have been created with topics ranging from the scale of the universe to how telescopes work. To qualify for these free Toolkits, clubs must be active in their communities, hosting two outreach events every three months or five outreach events within a calendar year. Supplemental toolkits were also created based on special events, such as the solar eclipses and the 50th anniversary of Apollo’s Moon landing. A new toolkit is in development to teach audiences about solar science, and NSN is on track to support clubs well into the future.
Rye Science Day, October 2014 Credit: Southern Colorado Astronomical Society/Malissa Pacheco NSN also hosts archived video trainings on these toolkits and other topics via its YouTube channel and a monthly webinar series with scientists from various institutions worldwide. Lastly, a monthly segment called Night Sky Notes is produced for clubs to share with their audiences via newsletters and mailing lists.
Sharing the Universe
In 2007, a National Science Foundation grant provided funding for further research into astronomy club needs. From that came three resources for clubs – the Growing Your Astronomy Club and Getting Started with Outreach video series, as well as an updated website with a national calendar and club and event coordination. Now you can find hundreds of events each month across the country, including virtual events that you can join from anywhere.
