Astronomers have shed further light on the evolution of the early Universe with the discovery of a “team” of super bright galaxies. For about 150 million years after the Big Bang, the Universe was a “dark” place, made of just H and He atoms, as the first stars had yet to be formed. This all changed with the first generation of stars, so bright and powerful that their light started to break apart hydrogen atoms around them, while their cores produced the elements essential for life itself.

By peering back through time, Dr David Sobral and his team at Lancaster University have now confirmed a sample of galaxies that are giving us a unique glimpse into that era...

After an almost 5-year journey, NASA’s Juno spacecraft successfully entered Jupiter’s orbit during a 35-minute engine burn. With its suite of 9 science instruments, Juno will investigate the existence of a solid planetary core, map Jupiter’s intense magnetic field, measure the amount of water and ammonia in the deep atmosphere, and observe the planet’s auroras. Confirmation of a successful orbit insertion was received from Juno tracking data monitored at JPL, CA and Lockheed Martin Juno operations center in Denver. The telemetry and tracking data were received by NASA’s Deep Space Network antennas in Goldstone, California, and Canberra, Australia.

ALMA finds a Swirling, Cool Jet that Reveals a Growing, Supermassive Black Hole

Alma's close-up view of the centre of galaxy NGC 1377 (upper left) reveals a swirling jet. In this colour-coded image, reddish gas clouds are moving away from us, bluish clouds towards us, relative to the galaxy's centre. The Alma image shows light with wavelength around one millimetre from molecules of carbon monoxide (CO). A cartoon view (lower right) shows how these clouds are moving, this time seen from the side. The background colour image of NGC 1377 and its surroundings is a composite made from a visible light images taken at the CTIO 1.5-metre telescope in Chile by H. Roussel et al. (2006) (V filter; http://adsabs.harvard.edu/abs/2006ApJ...646..841R), and in filters r and i by ESO's VLT Survey Telescope [VST] Credit: CTIO/H. Roussel et al./ESO (left panel); Alma/ESO/NRAO/S.

Timeline of key Jupiter milestones leading up to Juno’s arrival today

This visual timeline shows our evolving view of Jupiter and some of the key milestones leading up to one of the most ambitious Jupiter missions yet: Juno.

This visual timeline shows our evolving view of Jupiter and some of the key milestones leading up to one of the most ambitious Jupiter missions yet: Juno. NASA television coverage of the event begins at 10:30 pm US Eastern time. The solar-powered spacecraft is equipped with a suite of instruments to learn about how Jupiter formed, and a radiation vault to protect the electronics from massive doses of radiation near the gas giant, reaching 1,000 times the lethal level for a human.

Jupiter is the 5th planet from the sun...
