Flustered Imagination

Ancient Oceans on Mars

It is now widely accepted that Mars was once a very wet place. About four billion years ago Mars would have had enough water to cover its entire surface in a liquid layer about 140 metres deep. It is likely that the liquid would have pooled to form an ocean occupying almost half of Mars’s northern hemisphere, and in some regions reaching depths greater than 1.6 kilometres. This artist’s impression shows what the planet may have looked like with its ancient ocean. Imagine: could life have lived in such a place?

Rumours fly as physicists hint at the first ever observations of gravitational waves

And that’s a huge deal - if it’s true.

Earlier today, well-known American theoretical physicist Laurence Kraus tweeted that the results of a recent experiment looking for gravitational waves have finally been peer-reviewed and we just might have the first direct evidence that these light-speed ripples in the Universe actually exist.

If it turns out that we really do have definitive evidence that gravitational waves exist - the results of the study have not yet been released to the public - we’re looking at Nobel Prize-worthy stuff, but the team behind the experiment is urging everybody to be patient and not to jump to conclusions just yet, despite what’s going on in your Twitter feed.

“The official response is that we’re analysing the data,” Gabriela González, a physicist from Louisiana State University and spokesperson for the LIGO (Laser Interferometer Gravitational Wave Observatory) group that ran the experiments, told Nature when rumours started flying back in September.

The Vast Universe Captured In One Unbelievable Image

Some people find it difficult to imagine what the entire universe would look like. However, Pablo Carlos Budassi, a visionary artist, has stepped in and let his imagination wander as far as infinite space.

Keep reading to view a zoomed in short of the universe captured in one image, as well as to how the artist accomplished such ambitious task.

Galaxy quakes could improve hunt for dark matter

A trio of brightly pulsating stars at the outskirts of the Milky Way is racing away from the galaxy and may confirm a method for detecting dwarf galaxies dominated by dark matter and explain ripples in the outer disk of the galaxy. This new method to characterize dark matter marks the first real application of the field of galactoseismology. Just as seismologists analyze waves to infer properties about Earth’s interior, Sukanya Chakrabarti from the Rochester Institute of Technology uses waves in the galactic disk to map the interior structure and mass of galaxies. Her team used spectroscopic observations to calculate the speed of the three Cepheid variables — stars used as yardsticks to measure distance in galaxies — in the Norma constellation. Chakrabarti’s 2015 study used Cepheid variables to mark the location of a dark-matter-dominated dwarf galaxy approximately 300,000 light-years away. In contrast, the disk of the Milky Way terminates at 48,000 light-years. The current study tracks a cluster of Cepheids that are racing away at an average speed of 450,000 miles (724,000 kilometers) per hour, while the radial velocity of stars in the stellar disk of the Milky Way is about 13,000 miles (21,000 kilometers) per hour, Chakrabarti said. The method confirms her 2009 prediction.
