Hubble Looked as Far Back in Time as it Could, and Still Couldn?t See the First Generation of Stars in the Universe

   08 Jun 00:00:08  |  Universe Today

Astronomers don?t know exactly when the first stars formed in the Universe because they haven?t been observed yet. And now, new observations from the Hubble Space Telescope suggest the first stars and galaxies may have formed even earlier than previously estimated. Why? We *still* haven?t seen them, even with the best telescope we’ve got, pushed …

China will begin constructing its space station in 2021

   07 Jun 00:00:15  |  Universe Today

The Chinese space agency is building a brand new space station, and they’re going about it in a suitably impressive way: an ambitious schedule of 11 planned launches crammed into only two years. When it’s done, the 66-ton space station will host crews of three astronauts for up to six months at a time, lasting …

A New Telescope is Ready to Start Searching for Answers to Explain Dark Energy

   07 Jun 00:00:15  |  Universe Today

Back in 2015, construction began on a new telescope called the Dark Energy Spectroscopic Instrument (DESI). Later this year, it will begin its five-year mission. Its goal? To create a 3D map of the Universe with unprecedented detail, showing the distribution of matter. That detailed map will allow astronomers to investigate important aspects of cosmology, …

Interstellar Oumuamua Was a Dark Hydrogen Iceberg

   06 Jun 00:00:04  |  Universe Today

When Canadian astronomer Robert Weryk discovered `Oumuamua passing through our Solar System with the Pan-STARRS telescope, in October 2017, it caused quite a stir. It was the first interstellar object we’d ever seen coming through our neighbourhood. The excitement led to speculation: what could it be? There was lots of fun conjecture on its origins. …

Supermassive Black Holes Grew by Consuming Gas and Entire Stars

   06 Jun 00:00:04  |  Universe Today

Where do they come from, those beguiling singularities that flummox astrophysicists?and the rest of us. Sure, we understand the processes behind stellar mass black holes, and how they form from the gravitational collapse of a star. But what about the staggering behemoths at the center of galaxies, those supermassive black holes (SMBH) that can grow …

Spying a Rare ?Ring of Fire? Around Venus at Inferior Conjunction

   05 Jun 00:00:11  |  Universe Today

Amazing things happen in the day-to-day sky, often unseen and unwitnessed in our normal routine. Just such a ?non-event? happened this week, when Venus reached inferior conjunction between the Earth and the Sun on its race from the dusk to the dawn sky. And what?s more amazing, is the fact that some skilled observers followed this passage and caught sight of Venus as a tiny blazing ?ring of fire? silhouetted against the sky.

Astronomers Find the Source of the Huge Bubbles of Gas Flowing Out of the Milky Way, Still No Idea What Caused Them

   05 Jun 00:00:11  |  Universe Today

There’s an unusual paradox hampering research into parts of the Milky Way. Dense gas blocks observations of the galactic core, and it can be difficult to observe in visible light from our vantage point. But distant galaxies don’t always present the same obstacles. So in some ways, we can observe distant galaxies better than we …

About 3.5 Million Years Ago, a Stream of Gas Outside the Milky Way Would Have Lit Up the Night Sky

   04 Jun 00:00:04  |  Universe Today

It’s a truism to point out that modern humans have only been around for the blink of an eye, relative to the age of the Universe. But the Universe was an active place long before we were around to observe all of that activity. And about 3.5 million years ago, it’s possible?if only remotely?that our …

The dinosaur killing asteroid hit the Earth at the most devastating possible angle

   04 Jun 00:00:04  |  Universe Today

There are bad days, and then there are really bad days. 65 million years ago, life on Earth – especially if you were a dinosaur – experienced the worst possible bad day, as a giant meteor came crashing down to the surface of our planet, unleashing an inferno followed by decades of nuclear winter. And …
