Hubble Captures Young Stars Changing Their Environments
This NASA/ESA Hubble Space Telescope image features the nearest star-forming region to Earth, the Orion Nebula (Messier 42, M42), located some 1,500 light-years away. ESA/Hubble, NASA, and T. Megeath This NASA/ESA Hubble Space Telescope image peers into the dusty recesses of the nearest massive star-forming region to Earth, the Orion Nebula (Messier 42, M42). Just 1,500 light-years away, the Orion Nebula is visible to the unaided eye below the three stars that form the ‘belt’ in the constellation Orion. The nebula is home to hundreds of newborn stars including the subject of this image: the protostars HOPS 150 and HOPS 153.
These protostars get their names from the Herschel Orion Protostar Survey, conducted with ESA’s Herschel Space Observatory. The object visible in the upper-right corner of this image is HOPS 150: it’s a binary star system where two young protostars orbit each other. Each star has a small, dusty disk of material surrounding it. These stars gather material from their respective dust disks, growing in the process. The dark line that cuts across the bright glow of these protostars is a cloud of gas and dust falling in on the pair of protostars. It is over 2,000 times wider than the distance between Earth and the Sun. Based on the amount of infrared light HOPS 150 is emitting, as compared to other wavelengths it emits, the protostars are mid-way down the path to becoming mature stars.
Extending across the left side of the image is a narrow, colorful outflow called a jet. This jet comes from the nearby protostar HOPS 153, which is out of the frame. HOPS 153 is significantly younger than its neighbor. That stellar object is still deeply embedded in its birth nebula and enshrouded by a cloud of cold, dense gas. While Hubble cannot penetrate this gas to see the protostar, the jet HOPS 153 emitted is brightly and clearly visible as it plows into the surrounding gas and dust of the Orion Nebula.
The transition from tightly swaddled protostar to fully fledged star will dramatically affect HOPS 153’s surroundings. As gas falls onto the protostar, its jets spew material and energy into interstellar space, carving out bubbles and heating the gas. By stirring up and warming nearby gas, HOPS 153 may regulate the formation of new stars in its neighborhood and even slow its own growth.

The crew of a Surjet private air service flight had an unusual encounter on December 23 while returning to Fort Lauderdale. Flight attendant Cassandra Martin, along with two pilots, was onboard the aircraft flying over the Bahamas when an unexpected event caught their attention.
“I suddenly heard air traffic control say, ‘We have a foreign object; can you please identify it?'” Martin recounted to NBC Miami.
Curious, she looked out the window. “I glanced to the left, and the pilot noticed three objects, though I only saw one. I quickly grabbed my phone, pressed it against the window, and tried to record a video of the object,” she explained.
Martin described the orb as white, later shifting to a faint green hue, almost as though surrounded by an electric field. The object followed their flight for about 45 minutes before disappearing.
What made the sighting extraordinary was the altitude. The jet was cruising at approximately 43,000 to 45,000 feet, yet the orb was far above the aircraft and still managed to track it for the extended duration.
The orb’s speed and maneuverability ruled out possibilities such as a balloon or a consumer drone. Unless the orb is of extraterrestrial origin, the orb might be a craft or drone equipped with highly advanced technology not yet publicly known, akin to recent reports of sophisticated drones spotted across the U.S.
This remarkable incident follows a December 16, 2024 sighting aboard United Airlines flight UA2359 from Chicago to Newark. During that flight, a passenger filmed several unidentified orbs at altitudes between 40,000 and 50,000 feet. Additionally, reports surfaced from at least four commercial airline pilots who witnessed mysterious, colorful, circular lights moving at extreme speeds over Oregon in the same month.
These repeated sightings raise questions: Are they advanced black projects hidden from public knowledge or evidence of something extraterrestrial? Regardless of their origin, the increasing reports of advanced drones and strange orbs suggest that something significant is occurring. View the full article

A video taken by an airline passenger reportedly during a commercial flight over the UK shows what seem to be two figures standing on a layer of clouds.
The intriguing footage has sparked a wave of speculation online. While some viewers suggest the figures could be supernatural beings, closer analysis of the footage reveals additional shapes emerging through the clouds as the camera pans from left to right, image below.
This has led others to theorize that the "figures" might actually be exhaust stacks or other tall structures releasing steam, breaking through a fog layer and creating an illusion of human-like forms.
Rather than supernatural entities, the phenomenon is more likely an example of pareidolia, a psychological tendency to perceive familiar shapes, such as faces or figures, in random patterns.

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.
Want a quick and easy way to illustrate what opposition is for Jupiter, Saturn, Mars, or other outer worlds? Follow the instructions on our Toolkit Hack: Illustrating Opposition with Exploring the Solar System page using our Exploring Our Solar System activity!

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.
