New images have revealed detailed clues about how the first stars and structures were formed in the Universe and suggest the formation of the galaxy got off to a fitful start.

An international team of astronomers from the University of Nottingham and Centro de Astrobiología (CAB, CSIC-INTA) used data from the Hubble Space Telescope (HST) and the Gran Telescopio Canarias (GTC), the so-called Frontier Fields, to locate and study some of the smallest faintest galaxies in the nearby universe. This has revealed the formation of the galaxy was likely to be fitful. The first results have just been published in the journal Monthly Notices of the Royal Astronomical Society (MNRAS).

One of the most interesting questions that astronomers have been trying to answer for decades is how and when the first galaxies formed. Concerning the how, one possibility is that the formation of the first stars within galaxies started at a steady pace, slowly building up a more and more massive system. Another possibility is that the formation was more violent and discontinuous, with intense, but short-lived bursts of star formation triggered by events such as mergers and enhanced gas accretion.

And it’s based on a kind of plasma.

A new design of a plasma jet engine was unveiled last year by a group of researchers in China. While not a new technology in and of itself, this new design could be the secret to allowing the use of these engines in the atmosphere — not just limited to space.

While the thrust output is still pretty puny when compared to conventional atmospheric engines, once scaled, this new type of engine could prove revolutionary for the aerospace industry.

The first images are now coming through to NASA from this week’s flyby of Jupiter by its Juno spacecraft.

This latest close flyby is the 37th of the mission, but this basketball court-sized spacecraft’s images of the giant planet never cease to amaze.

This week’s images even include a rare photo of Jupiter’s moon Europa.

Right now the theme in space is not only billionaires crossing the Karman line… we are now looking to go further than we’ve ever ventured to study asteroids. Also, we’re trying a new tactic to see if we can successfully divert an asteroid from wiping us all out.
Lucy launched Saturday from Florida. Despite a problem with the solar array panels not latching completely, NASA is confident the mission won’t be severely impacted.
I also talked to Harvard astronomer Jonathan McDowell about the Double Asteroid Redirection Test or DART that is scheduled for November.
