NASA Dawn Reveals Recent Changes in Ceres

Observations of Ceres have detected recent variations in its surface, revealing that the only dwarf planet in the inner solar system is a dynamic body that continues to evolve and change. NASA’s Dawn mission has found recently exposed deposits that give us new information on the materials in the crust and how […]

Aussies May Get To See The Aurora Australis Tonight

Aussies May Get To See The Aurora Australis Tonight

A geomagnetic storm has been forecast to hit Earth this week, due to high speed solar wind streams resulting from a coronal hole. This all sounds very scary, and media coverage of the event has ranged from apocalyptic to promising a planet bathed in beautiful auroras, but the truth is a little less spectacular than […]

Geomagnetic Storm Watch: Solar Storm Expected To Hit Earth

PITTSBURGH (KDKA) – If you live in the northernmost parts of the United States, you might be in for a Northern Lights show Wednesday or Thursday.  The National Oceanic and Atmospheric Administration has issued a geomagnetic storm watch for March 14 and 15. NOAA says the minor storm is expected to cause escalated geomagnetic responses. States in the northern […]

Meet 'Steve,' the Aurora-Like Mystery Scientists Are Beginning to Unravel

Meet 'Steve,' the Aurora-Like Mystery Scientists Are Beginning to Unravel

New work helps to codify the cause and properties of “Steve,” an aurora-like phenomenon documented by citizen scientists as it streaked across the sky in western Canada. As of a new paper’s release today (March 14), the phenomenon has been dubbed STEVE, a backronym that matches the name originally given by aurora watchers. (STEVE is […]

How long does a galaxy take to rotate?

How long does a galaxy take to rotate?

For thousands of years, humans have measured time by the movement of the cosmos. A spin of the Earth is a day, an orbit of the moon is about a month and the Earth’s journey around the sun is a year. We might have to add a new cosmological measure to our calendars, because astronomers have discovered that […]

Get the Mach newsletter. SUBSCRIBE Even people who know little about Albert Einstein’s work know he was brilliant — so clever that his name is synonymous with genius. Of course, the mind that gave us the theory of general relativity, the 1915 masterwork that sealed Einstein’s scientific reputation, was human. And so Einstein made his […]

Albert Einstein

Today marks the birthday of one of the world’s most famous scientist Albert Einstein, who was born on 14 March 1879. The German-born physicist is best known for his general theory of relativity and the equation E=MC2. But what does the equation really mean? Put simply, the equation states that energy ‘stored’ in any object […]
