China announced on Wednesday that its Chang’e-4 lunar lander and rover is expected to land on the far side of the moon later this year.

Images displayed at a press conference in Beijing showed that the rover is a rectangular box with two folding solar panels and six wheels. It is 1.5 metres long, a metre wide and 1.1 metres high.

In a massive region of space, astronomers find far fewer galaxies than they expected
(3 UCLA scientists contribute to study that could change perception of how early universe evolved)

University of California astronomers, including three from UCLA, have resolved a mystery about the early universe and its first galaxies.

Astronomers have known that more than 12 billion years ago, about 1 billion years after the Big Bang, the gas in deep space was, on average, much more opaque than it is now in some regions, although the opacity varied widely from place to place. But they weren’t sure about what caused those variations.

To learn why the differences occurred, the astronomers used one of the world’s largest telescopes, the Subaru telescope on Mauna Kea in Hawaii, to search for galaxies of young stars in an exceptionally large region of space — 500 million light-years across — where they knew the intergalactic gas was extremely opaque.

If the region had an unusually small number of galaxies, the scientists would be able to conclude that starlight could not penetrate as far as expected through the intergalactic gas; if it had an unusually large number of galaxies, the implication would be that the region had cooled significantly over the previous several hundred million years. (Having few galaxies in a region would mean not only that there was less light created by those galaxies, but also that even more opaque gas was being formed, so the light could not travel as far as astronomers had expected.)

“It was a rare case in astronomy where two competing models, both of which were compelling in their own way, offered precisely opposite predictions, and we were lucky that those predictions were testable,” said Steven Furlanetto, a UCLA professor of astronomy and a co-author of the research.

The researchers found that region contains far fewer galaxies than expected — clear evidence that starlight could not get through. The paucity of galaxies could be the reason this region is so opaque.

“It is not that the opacity is a cause of the lack of galaxies,” Furlanetto said. “Instead, it’s the other way around.”

They concluded that because the gas in deep space is kept transparent by ultraviolet light from galaxies, fewer nearby galaxies might make it murkier.

Roughly 620 light-years from Earth, there is KELT-9b, a record exoplanet. This is the hottest gas giant exoplanet discovered so far, with a temperature of over 4,000 Kelvin (3,750°C/6,800°F) – hotter than many stars. Now astronomers have been able to study its atmosphere and have detected iron and titanium. 

As reported in Nature, this discovery is an important first in the studies of worlds outside the Solar System. Iron has never been detected in the atmosphere of an exoplanet before, although the element is the most abundant transition metal.

Finding the metal in the atmosphere wasn’t straightforward. Iron is usually highly refractive, so it doesn’t leave a strong fingerprint in the light we see coming from the planet. However, the researchers performed detailed simulations of what an extreme atmosphere like this should be like. This gave them confidence that it might be possible to see iron in the atmosphere of KELT-9b with current instruments.

"The results of these simulations show that most of the molecules found there should be in atomic form, because the bonds that hold them together are broken by collisions between particles that occur at these extremely high temperatures," co-author Kevin Heng, a professor at the University of Bern, said in a statement.

The team observed the planet as it passed in front of its star. During this transit, the light from the star is filtered through the planet's atmosphere, which astronomers can use to work out its chemical composition based on the light. The simulations suggested that iron vapor, if present, would leave a clear signature.

"With the theoretical predictions in hand, it was like following a treasure map," added lead author Jens Hoeijmakers, a researcher at the Universities of Geneva and Bern, "and when we dug deeper into the data, we found even more." The observation revealed that the planet also had titanium vapor in its atmosphere.

KELT-9b is an ultra-hot Jupiter, a class of incredibly high-temperature gas giant planets. These objects have complex atmospheres, partly like stars and partly like planets, so objects like KELT-9b are unique laboratories to study the evolution of atmospheres exposed to the extremes of the cosmos.

Pretty postcards. "What's new out at Jupiter? We haven't looked in on NASA’s Juno spacecraft since (checks blog archive) May. Juno completed its 14th close flyby of Jupiter on July 15, and as of Tuesday morning, it was 8 million kilometers from Jupiter, gradually working its way back toward the planet following apojove.

In general Jupiter news, astronomers have found 12 new Jovian moons, while one of Juno's instruments saw what may be a new volcano on Io!

And, of course, there are some recent pretty pictures from JunoCam, brought to you by image processors from around the world."
