NASA's Telescope Spots a Nebula That Looks Like a Hamburger!
HH 30, the hamburger nebula
Post Author - Ellis Nolan
They say art imitates life, but this month, it seems as though life imitates “Cloudy With a Chance of Meatballs.” February’s photo of the month from the James Webb Space Telescope depicts HH (Herbig-Haro Object) 30, a one-octillion-ton cloud of gas surrounding a fledgling star that also happens to resemble an iconic fast-food menu item.
Believe it or not, HH 30 is not the first astral occurrence to resemble food—notable others include the “Fried Egg Galaxy” and “Gomez’s Hamburger.” But how did it get to be that shape? Well, this particular outer space sandwich resides in a nebula, a large region made up of gas and cosmic dust where stars are born. In general, these regions are in a constant tug-of-war between the tendency of their own gravity to pull their forming material inward and the tendency of the gasses they contain to expand outward. If something upsets this push and pull, the nebula can collapse.

In this scenario, the gravity of the nebula “wins” the tug-of-war, causing the gasses and cosmic dust to collect and rise to extremely high temperatures, forming what is known as a “protostar,” a ball of gas and dust that is really hot but not yet achieving nuclear fusion. This protostar is what HH 30 surrounds and makes up the “patty” of the outer space burger.
The “bun” of the burger is material from HH 30 illuminated by the protostar at the center. Particularly notable about this Herbig-Haro Object is that some of the material seems to be drifting away (depicted in the bottom-left of the photo of the month)! Scientists aren’t quite sure why this is happening at the moment, but some have hypothesized that the protostar within HH 30 is actually part of a binary system with another star, which is leading the material in HH 30 astray.
Nebulae are simply fascinating environments. While the “patty” of the astral hamburger is still in its infancy, our Sun formed through the exact same process. Perhaps one day, astronauts will chow down on hamburgers in the orbit of the former HH 30. Order up!

Organic Glass Found Among Remains of Roman Guard
One of the most dramatic events in the history of the Roman Empire was the eruption of Mount Vesuvius in 79 CE. It is unknown how many perished during the eruption and its fallout, however, haunting images of contorted Pompeiians frozen in time by searing gas and ash paints an image of hellish, alien conditions. In a bizarre twist of the otherworldly occurrence, scientists have found the only documented instance of a victim whose brain was turned to glass by flows from the eruption.
The Mysterious Origin of the St. Mark's Square Lion!
Keeping a watchful eye over what Napoleon knew as “the drawing room of Europe,” the winged lion of St. Mark’s Square in Venice, Italy, is a majestic sight. The origin of this iconic statue has been cloaked in mystery, but in September of 2024, a group of chemists, archaeologists, geologists, and art historians shed more light on this sculpture’s story.

The Top 5 Most Expensive Star Wars Collectibles Ever Sold
When Star Wars debuted in theaters on May 25th, 1977, it launched an international phenomenon spanning decades of film history. Today, the series has had countless spinoffs, tv shows, books, and merchandising emblazoned with its characters and symbols, for which fans are ready to part with a pretty penny. Here are the top 5 most expensive Star Wars memorabilia items ever sold.
The Biggest Dinosaurs to Walk The Earth
For 165 million years across the Mesozoic Era, dinosaurs reached incredible, towering sizes, but curiously the evidence suggests the largest came at the end of the Age of Dinosaurs. This may seem ironic. After all, larger animals have smaller populations and require more food, thus making them susceptible to environmental stresses. On the flip side, if a large animal is able to survive a mass die-off, their genetic predisposition to a large size will quickly spread in a reduced population. This is what we see in the Late Cretaceous: dinosaurs of many different clades reaching their apex.
The Largest Meteorites Ever Discovered on Earth
Meteorites have fascinated humans since we first started looking up into the night sky. Since then, our ability to track and study them has greatly improved, but the fascination remains. Here is a countdown of the 5 largest meteorites ever found!
