The Rapid Changes We?re Seeing With the Earth?s Magnetic Field Don?t Mean the Poles are About to Flip. This is Normal

   13 Jun 20:00:16  |  Universe Today

One of the most interesting discoveries about Earth in the past few decades concerns the Earth’s magnetic poles. Paleomagnetic records show that the poles have flipped places 183 times in the last 83 million years. That’s about every 450,000 years on average, though there were ten million years between flips in at least two cases. …

Perseverance Has Been Carrying a Rock in its Wheel for Over 100 Days

   12 Jun 20:00:13  |  Universe Today

Why does a Mars rover have a rock in one of its wheels? Maybe it’s because a rover doesn?t have pockets. Who among us hasn?t picked up a great rock, carried it around, maybe saved it for a long time, or even placed it somewhere safe or special? The Perseverance rover is doing just that, …

Do Supermassive Black Holes Prematurely end Star Formation in Some Galaxies

   11 Jun 20:00:09  |  Universe Today

Some galaxies, like the Milky Way, have maintained regular star formation for billions of years. Others, like large elliptical galaxies, are “red and dead.” Star formation in those galaxies shut off long ago. Astronomers have long suspected the nefarious influence of supermassive black holes, and new research has found the smoking gun. An international team …

Hubble Pins Down the Mass of a Potential Free-Floating Black Hole That?s 5,000 Light-Years Away

   11 Jun 20:00:09  |  Universe Today

Earlier this year, astronomers used microlensing and the Hubble Space Telescope to detect, for the first time, a rogue black hole that is about 5,000 lightyears away from Earth. Now, with more precise measurements, they have been able to determine an approximate mass of this hard-to-detect object. However, the surprisingly low mass means there?s a …

Jupiter is up to 9% Rock and Metal, Which Means it Ate a lot of Planets in its Youth

   10 Jun 20:00:18  |  Universe Today

Jupiter is composed almost entirely of hydrogen and helium. The amounts of each closely conform to the theoretical quantities in the primordial solar nebula. But it also contains other heavier elements, which astronomers call metals. Even though metals are a small component of Jupiter, their presence and distribution tell astronomers a lot. According to a …

Venus Does Have Craters. Here?s one

   09 Jun 20:00:20  |  Universe Today

As most everyone knows, Venus is called Earth’s twin, though its scorching temperatures and extreme surface pressure are more like an evil twin. For a twin and our closest planetary neighbour, we don’t know it very well. Venus’ dense clouds keep the planet’s surface hidden in visible-light observations. It wasn’t until NASA’s Magellan spacecraft visited …

Which Missions and Observatories can Detect Technosignatures

   09 Jun 20:00:20  |  Universe Today

The search for technosignatures has always taken a back seat in the broad search for extraterrestrial life forms. Biosignatures, such as methane in an exoplanet?s atmosphere, have long been front and center. But while we are searching for signs of biology, signs of technology might be hiding in plain sight. According to a new report …
