By studying a nearby sun-like star, astronomers have concluded that the Sun is capable of releasing solar flares a thousand times greater than anything previously recorded. Scientists say the chances of this are quite slim, but warn that such an event would threaten life on Earth.
Sit back, relax, and look straight at the sun just this once.
A rather massive coronal hole was recently spotted on the Sun by NASA’s Solar Dynamics Observatory. The region—the size of 50 Earths—is spewing material into space at tremendous speeds. It may look terrifying, but astronomers say it’s nothing to worry about.
The Earth, right now, is revolving around the sun at about 62,000 miles per hour. But what would happen if we slowed to a stop? At that point, the planet would have exactly 64 1/2 days before it crashed into the sun. In this week’s episode, we find out what would happen during those 64 1/2 days.
The “blue moon” made news on Friday, but what about a blue sun? This eerie and gorgeous image of the sun was snapped on July 15 using the Extreme Ultraviolet Imager aboard NASA’s STEREO-A spacecraft, “which collects images in wavelengths of light that are invisible to the human eye.”
Yesterday, we looked at an interactive infographic on the relative orbits of everything in the solar system. Today, let’s compare the planets to one another. This site shows us how all of the solar system’s planets (and Pluto) stack up.
Space is really, really big, and there’s been a couple of great videos out there that show off the relative size of objects. This video puts the scale of the solar system into real perspective by showing how it takes you pass through the solar system at the speed of light.
Recent headlines are warning that the Earth will enter into a “mini ice age” in about 20 years because the sun is heading towards a period of very low output. Here’s why this scenario is extremely unlikely.
This fantastic compilation of solargraphs were taken with beer cans: homemade pinhole cameras with a paper negative inside. These sixteen were among the best that the Philippus Lansbergen Public Observatory in Middleburg, Netherlands received.
Our Sun has been quite active over the past several weeks, ejecting giant strands of stellar debris into the cosmos. NASA scientists recently captured a video of one particularly eye-catching explosion that produced a dramatic arch across the sun’s surface.
Since today was a monumental day for gay rights in America, it’s only fitting that we share this science image, showing all of the colors emitted by the sun. Why are there gaps in the spectrum? Those are our star’s missing colors. Read all about it here.
The European Space Agency's PROBA-2 minisatellite caught the March 20th solar eclipse, with the ESA creating a time-lapse video of its images. See the full video below, and images of it from the ISS.
This puts everything in perspective. Here's an image of today's X2.2-class solar flare, along with the Earth for scale. Image via NASA/Solar Dynamics Observatory
The Solar & Heliospheric Observatory (SOHO) project satellite captured this dazzling, hypnotic footage of a solar eruption yesterday.
When you are looking at a specific kind of red light emitted by hydrogen. This color-inverted photo was taken in October of last year by the Big Bear Solar Observatory's 1.6 meter New Solar Telescope. They say it looks like a rose, but I definitely see a thistle.
This photo, taken last week by NASA's Solar Dynamics Observatory (SDO), shows a "filament" of cooler solar material hovering over the surface of the sun. The effect is of a huge crack across the sun, as if something is preparing to burst out.
To celebrate the fifth anniversary of NASA's Solar Dynamics Observatory, NASA put out this video of all the coolest, jaw dropping explosions that happened on our Sun over the past five years. You basically watch the Sun dances with shooting flares and solar loops. It's unreal.
Scientists working at the Solar Dynamics Observatory have spotted a massive solar filament that stretches across a good portion of the sun's visible surface. It's about 533,000 miles long (857,780 km) – equivalent to 67 Earths lined up in a row.
What would it look like if other stars were as close as the sun? For starters, we may have more than one, and it may be either much bigger or smaller than our current orbital star, as shown in these videos, which explore a hypothetical universe where our sun has been replaced with other stars and our moon with planets.
