Tiny Object Found at the Edge of the Solar System for the First Time. A Kuiper Belt Object that’s Only 2.6 km Across The Kuiper Belt, or the Edgeworth-Kuiper Belt, is home to ancient rocks. Kuiper Belt Objects, or KBOs, are remnants of the early planet-formation days of our Solar System. Small KBOs, in the 1 km. diameter range, have been theorized about for decades, but nobody’s every found one. Until now. Planets form when bits of dust … Continue reading “Tiny Object Found at the Edge of the Solar System for the First Time. A Kuiper Belt Object that’s Only 2.6 km Across” TheRead More →

Without the Impact that Formed the Moon, We Might Not Have Life on Earth The Earth wasn’t formed containing the necessary chemicals for life to begin. One well-supported theory, called the “late veneer theory”, suggests that the volatile chemicals needed for life arrived long after the Earth formed, brought here by meteorites. But a new study challenges the late veneer theory. Evidence shows that the Moon was created when … Continue reading “Without the Impact that Formed the Moon, We Might Not Have Life on Earth” The post Without the Impact that Formed the Moon, We Might Not Have Life on Earth appeared first onRead More →

Quasars with a Double-Image Gravitational Lens Could Help Finally Figure out how Fast the Universe is Expanding How fast is the Universe expanding? That’s a question that astronomers haven’t been able to answer accurately. They have a name for the expansion rate of the Universe: The Hubble Constant, or Hubble’s Law. But measurements keep coming up with different values, and astronomers have been debating back and forth on this issue for decades. … Continue reading “Quasars with a Double-Image Gravitational Lens Could Help Finally Figure out how Fast the Universe is Expanding” The post Quasars with a Double-Image Gravitational Lens Could Help Finally Figure outRead More →

A Planetary Nebula Like This Will Only be Visible for About 10,000 Years Before it Fades Away For some stars, their last act is a final exhalation of gases, which we call a planetary nebula. While a living being’s last breath is closely followed by death, a star can continue to shine. And that shining illuminates the final exhalation of gases like a cosmic, diaphanous veil. Astronomers have captured one such planetary … Continue reading “A Planetary Nebula Like This Will Only be Visible for About 10,000 Years Before it Fades Away” The post A Planetary Nebula Like This Will Only be Visible for AboutRead More →

Blue Origin has Shown off a New Video of its New Glenn Rocket Design Blue Origin, the private aerospace company founded by multi-billionaire (and founder of Amazon) Jeff Bezos, is looking to make its presence felt in the rapidly expanding NewSpace industry. To this end, Blue Origin has spent years developing a fleet of reusable rockets that they hope will someday rival those of their greatest competitor, SpaceX. So … Continue reading “Blue Origin has Shown off a New Video of its New Glenn Rocket Design” The post Blue Origin has Shown off a New Video of its New Glenn Rocket Design appeared first onRead More →

One of Our Best Views of the Supermassive Black Hole at the Heart of the Milky Way An almost unimaginably enormous black hole is situated at the heart of the Milky Way. It’s called a Supermassive Black Hole (SMBH), and astronomers think that almost all massive galaxies have one at their center. But of course, nobody’s ever seen one (sort of, more on that later): It’s all based on evidence other than … Continue reading “One of Our Best Views of the Supermassive Black Hole at the Heart of the Milky Way” The post One of Our Best Views of the Supermassive Black Hole atRead More →

SpaceX Starhopper Damaged in High Winds Elon Musk indicates that the SpaceX Starhopper has been damaged after being toppled in 50 mile-per-hour winds. This will take a few weeks to repair.

A Disc of Icy Material, not Planet 9, Might Explain the Strange Movements in the Outer Solar System Is there or isn’t there a Planet 9? Is there a planet way out on the outskirts of our Solar System, with sufficient mass to explain the movements of distant objects? Or is a disc of icy material responsible? There’s no direct evidence yet of an actual Planet 9, but something with sufficient mass is … Continue reading “A Disc of Icy Material, not Planet 9, Might Explain the Strange Movements in the Outer Solar System” The post A Disc of Icy Material, not Planet 9, MightRead More →

Saturn’s Rings are Only 10 to 100 Million Years Old Can you imagine the Solar System without Saturn’s rings? Can you envision Earth at the time the dinosaurs roamed the planet? According to a new paper, the two may have coincided. Data from the Cassini mission shows that Saturn’s rings may be only 10 to 100 million years old. They may not have been there … Continue reading “Saturn’s Rings are Only 10 to 100 Million Years Old” The post Saturn’s Rings are Only 10 to 100 Million Years Old appeared first on Universe Today.

Geothermal Heating Could Make Life Possible on the Super Earth Planet at Barnard’s Star In 2018, scientists announced the discovery of a extrasolar planet orbiting Barnard’s star, an M-type (red dwarf) that is just 6 light years away. Using the Radial Velocity method, the research team responsible for the discovery determined that this exoplanet (Barnard’s Star b) was at least 3.2 times as massive as Earth and experienced average … Continue reading “Geothermal Heating Could Make Life Possible on the Super Earth Planet at Barnard’s Star” The post Geothermal Heating Could Make Life Possible on the Super Earth Planet at Barnard’s Star appeared first onRead More →
