Solar power is the fastest-growing form of renewable energy and currently accounts for 3.6% of global electricity production today. This makes it the third largest source of the renewable energy market, followed by hydroelectric power and wind. These three methods are expected to grow exponentially in the coming decades, reaching 40% by 2035 and 45% by 2050. Altogether, renewables are expected to account for 90% of the energy market by mid-century, with solar accounting for roughly half. However, several technical challenges and issues need to be overcome for this transition to occur.

Sometimes an image is so engrossing that we can ignore what it’s telling us about its subject and just enjoy the splendour. That’s certainly true of this image of NGC 5068 released by the ESA. But Universe Today readers are curious, and after enjoying the galactic portrait for a while, they want to know more.

Gravitational wave (GW) observatories have been a great addition to cosmologists’ arsenal in the lack decade. With their first effective detection at the Laser Interferometric Gravitational Observatory completed in 2015, they opened up a whole new world of data collection for scientists. However, so far, they haven’t solved one of the fundamental problems at the heart of their discipline – the “Hubble tension.” Now a new paper discusses the possibility of utilizing a network of new, space-based gravitational wave observatories to get closer than ever to the real value of one of the most important numbers in the Universe.

Despite all the hype surrounding the coming of the commercial space age, NASA and other governmental agencies will still play a vital role in the early stages of getting much of the infrastructure up and running before commercial actors can come in. That role will primarily be filled by being the first (and sometimes only) customer for a wide variety of companies that hope to profit from exploiting space resources. 

While the SpaceX Crew Dragon is making regular trips to and from the International Space Station, the other vehicle NASA was planning to rely on for crew transportation keeps running into problems and delays. Boeing and NASA just announced another set of delays for the CST-100 Starliner spacecraft, pushing it even further back from its proposed July launch window — which was already years behind schedule.

While Jupiter’s Great Red Spot is one of the most well-known spectacles in the solar system, Jupiter’s clouds and stripes that are responsible for the planet’s weather patterns are highly regarded, as well. Though not nearly as visible in an amateur astronomy telescope, Jupiter’s multicolored, rotating, and swirling cloud stripes are a sight to behold for any astronomy fan when seen in up-close images. And, what makes these stripes unique is they have been observed to change color from time to time, but the question of what causes this color change to occur has remained elusive.
