Have you heard of polyurethanes? As you read this, you’re undoubtedly close to some, or maybe sitting on them: this versatile class of chemicals is used for everything from padding your couch to insulating your windows, packaging food to carpet underlay, electronics casings to skateboard wheels. They also have vital uses in space, triggering a new ESA Clean Space project aiming to manufacture them in a greener way.

An international team led by Dutch astronomers has, after years of searching and defying the boundaries of a telescope, for the first time directly captured polarized light from an exoplanet. They can deduct from the light that a disk of dust and gas is orbiting around the exoplanet in which moons are possibly forming. The researchers will soon publish their findings in the journal Astronomy and

When in space, astronauts typically eat dehydrated, nutrient-dense food, but when it comes to longer space missions, that can become a problem as they'll eventually lack nutrients from fresh vegetables. However, one chemical and biomolecular engineering professor will be researching ways astronauts can grow their own fresh vegetables more efficiently while they are on missions.

The U.S. departments of Defense and Commerce will jointly seek public input on development of 5G communication networks, they announced on Monday.
5G, or fifth generation telecommunications standard for broadband cellular networks, offers higher download speeds and has been of particular interest to the U.S. military prior to its civilian rollout in 2019.

The most distant quasar known has been discovered. The quasar, seen just 670 million years after the Big Bang, is 1000 times more luminous than the Milky Way, and is powered by the earliest known supermassive black hole, which weighs in at more than 1.6 billion times the mass of the Sun.

Our astronomers have looked nine billion years into the past to find evidence that galaxy mergers in the early universe could shut down star formation and affect galaxy growth.
Using a powerful Earth-based telescope they saw that a huge amount of star-forming gas was ejected into the universe by the coming together of two galaxies.

To celebrate a new year, the NASA/ESA Hubble Space Telescope has published a montage of six beautiful galaxy mergers. Each of these merging systems was studied as part of the recent HiPEEC survey to investigate the rate of new star formation within such systems. These interactions are a key aspect of galaxy evolution and are among the most spectacular events in the lifetime of a galaxy.

The brown dwarf closest to our solar system hosts wind bands and jet streams, according to new analysis of the object's atmosphere.
Brown dwarfs are too big to be planets but not quite massive enough to generate fusion, a prerequisite for stellar classification. Though hot in their infancy, brown dwarfs steadily cool as they mature, making them difficult to spot and study.
