Black Holes and Revelations

Black Holes and Revelations

It sounds crazy. In new years, scientists have reliable a conspicuous couple between two kinds of objects that should, by all rights, have zero to do with any other: black holes and bizarre metals. The former are the famous guzzlers of low space, means to swallow anything — including stars, planets and even light itself […]

Finding the Universe’s Missing Matter

Finding the Universe’s Missing Matter

It’s a surprisingly big deal. This normal matter, the forms of particles that make up you and me and all astronomers can see in the universe, seemed to be escaped detection. The poser of this blank things strictly began in the early 1990s when scientists first tallied up all the stars, prohibited gas, cold dirt […]

Cassini’s Closing Act

Cassini’s Closing Act

Cassini is using out of gas. So before goal managers remove control, they’ve directed the booster on a no-return march into Saturn’s atmosphere, where it’s scheduled to burn up Sept. 15 at about 3:45 a.m. PDT. The pierce is precautionary. A dead spacecraft carrying stowaway microbes could pervert icy Enceladus, a moon Cassini showed us […]

Solar Eclipse Geometry

Solar Eclipse Geometry

On Aug. 21, the dim middle prejudiced of the moon’s shade will brush opposite the United States, formulating a sum solar obscure for regions in 14 states. But, you may ask, the object is so much incomparable than the moon, so how does this work? While the daytime star has a hole about 400 times […]

Total Eclipse: Solar Research Thrives in Darkness

Total Eclipse: Solar Research Thrives in Darkness

Sunspots, which seem as dim rags on the sun’s surface, called the photosphere, imply heated captivating activity. At 7,000 degrees Fahrenheit, these areas are cooler, and so darker, than the surrounding surface area, which can strech temperatures of 10,000 degrees Fahrenheit.   Sunspot activity waxes and wanes during an 11-year cycle. During the solar maximum, […]

Everything Worth Knowing About … Surviving Space

The Problem: Coming Down Is Hard to Do Floating in space may demeanour fun, but it’s also problematic. Humans, plants and other animals all grown to tarry 1 g of force, the normal sobriety they feel at Earth’s surface. The physique does reduction work in 0 gravity, and returning to normal sobriety strains muscles, hearts […]

Everything Worth Knowing About … the Dark Universe

Everything Worth Knowing About … the Dark Universe

How Do We Know It’s There? Space telescopes study the Big Bang’s vestige deviation (the vast x-ray background) have found the star is almost ideally flat. That means light travels in true lines unless it encounters mass. Scientists contend this only really creates clarity in a star packed with some kind of dim energy. Dark […]

Everything Worth Knowing About … Alien Contact

Searches Past and Present 1960 Astronomer Frank Drake performs the first complicated SETI experiment, called Project Ozma (after a Wizard of Oz character). With an 85-foot radio telescope in Green Bank, W.Va., he looks at two sunlike stars for signs of visitor technology. 1961 A tiny SETI discussion takes place in Green Bank, at which Drake presents […]

How Big is the Biggest Possible Planet?

How Big is the Biggest Possible Planet?

KELT-11b, one of the physically largest objects known, is 40 percent wider than Jupiter and has the firmness of styrofoam. (Credit: Walter Robinson/Lehigh University) Last week, a group of astronomers reported the first intensity find of an exomoon–a satellite orbiting a world around another star. Part of what is so distinguished about the report is […]

Everything Worth Knowing About … Asteroids

Everything Worth Knowing About … Asteroids

Our early solar complement was a furious place. Dust grains grew into pebbles, and pebbles became world-building planetesimals. These rocks spun around and bumped into any other in a pell-mell dance that left a route of waste in its wake. The ruins of these festivities sojourn strewn about the vast backyard. Many hilly and lead […]
