A Disc of Icy Material, not Planet 9, Might Explain the Strange Movements in the Outer Solar System

   27 Jan 01:00:01   |  Universe Today

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 …

Quasars with a Double-Image Gravitational Lens Could Help Finally Figure out how Fast the Universe is Expanding

   26 Jan 01:00:01   |  Universe Today

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. …

A Planetary Nebula Like This Will Only be Visible for About 10,000 Years Before it Fades Away

   25 Jan 01:00:01   |  Universe Today

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 …

One of Our Best Views of the Supermassive Black Hole at the Heart of the Milky Way

   24 Jan 01:00:01   |  Universe Today

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 …
