An instrument on our Solar Dynamics Observatory (SDO) captured its 100 millionth image of the sun. The instrument is the Atmospheric Imaging Assembly, or AIA, which uses four telescopes working parallel to gather eight images of the sun – cycling through 10 d…

A "transit of Venus" occurs when the planet Venus passes directly between the sun and the Earth. During the event, Venus will be seen from Earth as a small black sphere moving across the face of the sun. Such an event won’t occur again until the ye…
Ver en NASA ↗NASA's Solar Dynamics Observatory (SDO) zoomed in almost to its maximum level to watch tight, bright loops and much longer, softer loops shift and sway above an active region on the sun, while a darker blob of plasma in their midst was pulled about every whic…
Ver en NASA ↗Magnetic Dance: Solar material traces out giant magnetic fields soaring through the sun to create what's called coronal loops. Here they can be seen as white lines in a sharpened AIA image from Oct. 24, 2014, laid over data from SDO's Helioseismic Magnetic Im…
Ver en NASA ↗The sun emitted a mid-level solar flare, peaking at 11:24 p.m. EST on Jan. 12, 2015. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a f…
Ver en NASA ↗This close-up image of the sun presents an active region in profile as it rotated out of view. We can observe both the bright arching field lines and smaller pieces of darker matter in their midst being pulled back and forth just above the Sun's surface over …
Ver en NASA ↗Spectacular eruption: On June 7, 2011, SDO captured this image as a massive eruption lifted an enormous amount of cool, dark material into the corona. Most of that material fell back onto the sun, where the gravitational energy of the fall caused it to heat u…
Ver en NASA ↗How did scientists know that NASA Voyager spacecraft entered interstellar space? Increase in the density of charged particles was the key piece of evidence. Our sun sits in a bubble, called the heliosphere, carved out by wind emitted from the hot sun.
Ver en NASA ↗This artist concept shows the planet catalogued as 2003UB313 at the lonely outer fringes of our solar system. Our Sun can be seen in the distance. The new planet is at least as big as Pluto and about three times farther away from the Sun than Pluto.
Ver en NASA ↗This artist concept shows the general locations of NASA two Voyager spacecraft. Voyager 1 top has sailed beyond our solar bubble into interstellar space. Voyager 2 bottom is still exploring the outer layer of the solar bubble.
Ver en NASA ↗Radio telescopes cannot see Voyager 1 in visible light, but rather see the spacecraft signal in radio light. This image of Voyager 1 signal on Feb. 21, 2013. At the time, Voyager 1 was 11.5 billion miles 18.5 billion kilometers away.
Ver en NASA ↗This artist concept shows the outer layers of our solar bubble, or heliosphere, and nearby interstellar space. NASA Voyager 1 is currently exploring a region of interstellar space.
Ver en NASA ↗This visual represents sounds captured of interstellar space by NASA Voyager 1 spacecraft. Voyager 1 plasma wave instrument detected the vibrations of dense interstellar plasma.
Ver en NASA ↗This artist concept depicts NASA Voyager 1 spacecraft entering interstellar space. Interstellar space is dominated by the plasma, or ionized gas, that was ejected by the death of nearby giant stars millions of years ago.
Ver en NASA ↗This image from a set of animations show NASA Voyager 1 spacecraft exploring a new region in our solar system called the magnetic highway.
Ver en NASA ↗This artist concept shows NASA Voyager 1 spacecraft in a new region at the edge of our solar system where there are fewer low energy particles that originate from inside our solar system.
Ver en NASA ↗This artist concept shows NASA Voyager spacecraft against a backdrop of stars.
Ver en NASA ↗This composite image combines NASA Extreme Ultravoilet Imaging Telescope images from three wavelengths into one that reveals solar features unique to each wavelength.
Ver en NASA ↗This schematic shows our solar bubble moving through nearby interstellar space, or the space between stars.
Ver en NASA ↗This artist concept shows NASA Voyager 1 spacecraft in a new region at the edge of our solar system where the amount of high-energy particles diffusing into our solar system from outside has increased.
Ver en NASA ↗The image taken by the Oschin Schmidt Telescope, shows the star AC +79 3888, also known as Gliese 445. NASA Voyager 1 spacecraft, which is on a trajectory out of our solar system, is headed toward an encounter with AC +79 3888 circled in red.
Ver en NASA ↗Voyager 1 has entered interstellar space. NASA spacecraft, which rose from Earth on a September morning 36 years ago, has traveled farther than anyone, or anything, in history.
Ver en NASA ↗CAPSTONE, a microwave oven-sized CubeSat, will fly in cislunar space – the orbital space near and around the Moon. The mission will demonstrate an innovative spacecraft-to-spacecraft navigation solution at the Moon from a near rectilinear halo orbit slated fo…
Ver en NASA ↗NASA Phoenix Mars Lander will open its solar arrays 20 minutes after it touches down on the surface of Mars.
