Jupiter's clouds of many colors are seen in this image from our Juno spacecraft as it was racing away from the planet following its seventh close pass on May 19, 2017, from about 29,100 miles (46,900 km) above the cloud tops. Take a look: http://go.nasa.gov/2sBD1SQ

The clusters of monster stars that lit up the early universe

The first stars in the Universe were born several hundred million years after the Big Bang, ending a period known as the cosmological 'dark ages' – when atoms of hydrogen and helium had formed, but nothing shone in visible light.

Now two Canadian researchers have calculated what these objects were like: they find that the first stars could have clustered together in phenomenally bright groups, with periods when they were as luminous as 100 million Suns. Alexander DeSouza and Shantanu Basu, both of the University of Western Ontario in Canada, publish their results in a paper in Monthly Notices of the Royal Astronomical Society.

The two scientists modelled how the luminosity of the stars would have changed as they formed from the gravitational collapse of disks of gas. The early evolution turns out to be chaotic, with clumps of material forming and spiralling into the centre of the disks, creating bursts of luminosity a hundred times brighter than average. These first stars would have been at their brightest when they were 'protostars', still forming and pulling in material.

In a small cluster of even 10 to 20 protostars, the ongoing bursts would mean the cluster would spend large periods with enhanced brightness. According to the simulation, every so often a cluster of 16 protostars could see its luminosity increase by a factor of up to 1000, to an extraordinary 100 million times the brightness of the Sun.

The earliest stars lived very short lives and produced the first heavy elements, like the carbon and oxygen that the chemistry of life depends upon.

Light from these stars has travelled towards us for almost 13 billion years, so to observers on Earth they look very faint and also have their light stretched out into infrared wavelengths by the expansion of the universe. This makes these stars very hard to observe, but the next generation James Webb Space

Telescope (JWST) will survey the skies to look for them. Although the luminosity of an individual first star is probably too faint for JWST to spot it, the new work suggests that clusters of the first protostars could be prominent beacons in the early universe.

South Dakota Aurora

"The most unique display I've seen in South Dakota. A strong, leaving arc of light in the west northwest and continuing directly overhead. Also a strong and steady pale green arc on the northern horizon."

Due to the presence of a black hole in the center of the galaxy, the behemoth galaxy NGC 1275 is a strong emitter of X-rays. About 250 million light years away, it lies at the center of a cluster of galaxies known as the Perseus Cluster.
