Astronomers have discovered the surviving core of a gas giant, orbiting a distant star. The discovery provides a unique opportunity to analyse the interior of a planet first-hand.
NASA has released a stunning 61-minute time-lapse video that shows a decade in the life of the sun.
The video was created from images taken by NASA’s Solar Dynamics Observatory.
“From its orbit in space around Earth, SDO has gathered 425 million high-resolution images of the Sun, amassing 20 million gigabytes of data over the past 10 years,” explained NASA in a statement on its website. “This 10-year time lapse showcases photos taken at a wavelength of 17.1 nanometers, which is an extreme ultraviolet wavelength that shows the Sun’s outermost atmospheric layer – the corona.”
The Hubble Space Telescope has been enhancing our understanding of the universe through breathtaking images for 30 years — PBS Digital Studios celebrates Hubble’s 30th anniversary.
