Astronomers found a strange dwarf world that provides even more evidence that a giant planet is lurking at the edge of our solar system.

There might be a large planet lurking somewhere at the very edge of our solar system, and astronomers are hunting for it. While they have yet to find direct evidence of the planet, a recent discovery provides yet more indirect evidence that the planet does, in fact, exist. Astronomers found a small solar system body with a strange orbit that they say can only be explained by another, bigger planet hiding out there somewhere.

Is there enough space for all the wind turbines and solar panels to provide all our energy needs? What happens when the sun doesn’t shine and the wind doesn’t blow? Won’t renewables destabilise the grid and cause blackouts?

In a review paper last year in the high-ranking journal Renewable and Sustainable Energy Reviews, researcher Benjamin Heard and colleagues presented their case against 100 percent renewable electrical systems. They doubted the feasibility of many of the recent scenarios for high shares of renewable energy, questioning everything from whether renewables-based systems can survive extreme weather events with low sun and low wind, to the ability to keep the grid stable with so much variable generation.

Now, scientists have hit back with their response to the points raised by Heard and colleagues. The researchers from the Karlsruhe Institute of Technology and collaborators have analysed hundreds of studies to answer each of the apparent issues. They demonstrate that there are no roadblocks to a 100 percent renewable future.

VR companies around the world are planning to offer live views of the Earth from space within the next few years.

Capitalizing on the unparalleled sharpness and spectral range of NASA’s Hubble Space Telescope, an international team of astronomers is releasing the most comprehensive, high-resolution ultraviolet-light survey of nearby star-forming galaxies.

The researchers combined new Hubble observations with archival Hubble images for 50 star-forming spiral and dwarf galaxies in the local universe, offering a large and extensive resource for understanding the complexities of star formation and galaxy evolution. The project, called the Legacy ExtraGalactic UV Survey (LEGUS), has amassed star catalogs for each of the LEGUS galaxies and cluster catalogs for 30 of the galaxies, as well as images of the galaxies themselves. The data provide detailed information on young, massive stars and star clusters, and how their environment affects their development.

“There has never before been a star cluster and a stellar catalog that included observations in ultraviolet light,” explained survey leader Daniela Calzetti of the University of Massachusetts, Amherst. “Ultraviolet light is a major tracer of the youngest and hottest star populations, which astronomers need to derive the ages of stars and get a complete stellar history. The synergy of the two catalogs combined offers an unprecedented potential for understanding star formation.”

China and India are going to build a Lunar base/colony (I’ve heard) and the Japanese (I’ve heard) want to clad the moon in solar cells and microwave the power to Earth. To different places round the globe depending on the time.

In May 2018, China wrapped up a yearlong mission inside “Lunar Palace 1,” a Beijing facility designed to help the nation prepare to but boots on the moon. See images of the experiment here. (Read our full story here.) Here: Four volunteers take the oath in front of Lunar Palace 1, a facility for conducting bio-regenerative life-support systems experiments key to setting up a lunar base, at the Beijing University for Aeronautics and Astronautics (BUAA) on May 10, 2017. A ceremony was held in the BUAA that day as eight volunteers in two groups started a 365-day experiment in Lunar Palace 1.

An international team of astronomers has identified a rare laser phenomenon shining from the heart of the planetary nebula Menzel 3, otherwise known as the Ant Nebula. The discovery suggests the presence of an as yet unseen companion star, hiding at the core of the chaotic cosmic structure.

Menzel 3 is located roughly 8,000 light years from Earth in the direction of the constellation Norma. Discovered by Donald Menzel in the 1920s, it was given the moniker of the Ant Nebula, owing to its apparent similarity to the head and thorax of a garden ant.

The striking object belongs to a specific family of diffuse bodies known as planetary nebula. Despite their suggestive name, the formation of these beautiful structures has nothing to do with planets, and is instead rooted in the demise of middleweight stars similar to our Sun.

After two years in development, Project MELT (Manufacturing of Experimental Layer Technology) has resurfaced with a prototype microgravity 3D printer.

Made for the European Space Agency (ESA) the Additive Layer Manufacturing (ALM) breadboard machine is designed to 3D print high performance polymers aboard the International Space Station (ISS) and other off-world locations.

Don’t panic.

An asteroid the size of the Statue of Liberty is set to narrowly miss Earth on Tuesday evening. Luckily, it won’t actually smack into our planet or cause any da.
