 Who owns the moon? A space lawyer answers

Most likely, this is the best-known picture of a flag ever taken: Buzz Aldrin standing next to the first U.S. flag planted on the Moon. For those who knew their world history, it also rang some alarm bells. Only less than a century ago, back on Earth, planting a national flag in another part of the world still amounted to claiming that territory for the fatherland. Did the Stars and Stripes on the moon signify the establishment of an American colony?

Nasa’s James Webb Space Telescope will inspect the atmospheres of distant gas giants

Nasa’s James Webb Space Telescope will inspect the atmospheres of distant gas giants

The James Webb Space Telescope is like the party of the century that keeps getting postponed. Due to its sheer complexity and some anomalous readings that were detected during vibration testing, the launch date of this telescope has been pushed back many times – it is currently expected to launch sometime in 2021. But for obvious reasons, NASA remains committed to seeing this mission through.

New VLT Adaptive Optics Generarte Super-Crisp Images of Neptune Showing How Far Our Telescopes Have Come

New VLT Adaptive Optics Generarte Super-Crisp Images of Neptune Showing How Far Our Telescopes Have Come

ESO’s Very Large Telescope (VLT) has achieved first light with a new adaptive optics mode called laser tomography — and has captured remarkably sharp test images of the planet Neptune, star clusters and other objects. The pioneering MUSE instrument in Narrow-Field Mode, working with the GALACSI adaptive optics module, can now use this new technique to correct for turbulence at different altitudes in the atmosphere. It is now possible to capture images from the ground at visible wavelengths that are sharper than those from the NASA/ESA Hubble Space Telescope. The combination of exquisite image sharpness and the spectroscopic capabilities of MUSE will enable astronomers to study the properties of astronomical objects in much greater detail than was possible before.

NASA simulation shows how Europa’s “fossil ocean” rises to the surface over time

NASA simulation shows how Europa’s “fossil ocean” rises to the surface over time

In the 1970s, the Jupiter system was explored by a succession of robotic missions, beginning with the Pioneer 10 and 11 missions in 1972/73 and the Voyager 1 and 2 missions in 1979. In addition to other scientific objectives, these missions also captured images of Europa’s icy surface features, which gave rise to the theory that the moon had an interior ocean that could possibly harbor life.

NASA Juno Data Indicate Another Possible Volcano on Jupiter Moon Io

NASA Juno Data Indicate Another Possible Volcano on Jupiter Moon Io

Data collected by NASA’s Juno spacecraft using its Jovian InfraRed Auroral Mapper (JIRAM) instrument point to a new heat source close to the south pole of Io that could indicate a previously undiscovered volcano on the small moon of Jupiter. The infrared data were collected on Dec. 16, 2017, when Juno was about 290,000 miles (470,000 kilometers) away from the moon.

New telescope will scan the skies for asteroids on collision course with Earth

 New telescope will scan the skies for asteroids on collision course with Earth

Around sunrise on Feb. 15, 2013, an extremely bright and otherworldly object was seen streaking through the skies over Russia before it exploded about 97,000 feet above the Earth’s surface. The resulting blast damaged thousands of buildings and injured almost 1,500 people in Chelyabinsk and the surrounding areas. While this sounds like the first scene of a science fiction movie, this invader wasn’t an alien spaceship attacking humanity, but a 20-meter-wide asteroid that had collided with the Earth.

A New Cloaking Approach Could Potentially Make Objects Invisible From Every Direction

A New Cloaking Approach Could Potentially Make Objects Invisible From Every Direction

A BREAKTHROUGH. Researchers from Montreal’s National Institute of Scientific Research (INRS) just published a study in Optica detailing a new approach to invisibility cloaking. Their device, called a spectral invisibility cloak, is the first to manipulate the color (or frequency) of the light waves that interact with an object, rendering it invisible.

New insights into what might have smashed Uranus over onto its side

New insights into what might have smashed Uranus over onto its side

The gas/ice giant Uranus has long been a source of mystery to astronomers. In addition to presenting some thermal anomalies and a magnetic field that is off-center, the planet is also unique in that it is the only one in the Solar System to rotate on its side. With an axial tilt of 98°, the planet experiences radical seasons and a day-night cycle at the poles where a single day and night last 42 years each.

Instead of building single monster scopes like james webb, what about swarms of space telescopes working together?

Instead of building single monster scopes like james webb, what about swarms of space telescopes working together?

In the coming decade, a number of next-generation instruments will take to space and begin observing the Universe. These will include the James Webb Space Telescope (JWST), which is likely to be followed by concepts like the Large Ultraviolet/Optical/Infrared Surveyor (LUVOIR), the Origins Space Telescope (OST), the Habitable Exoplanet Imager (HabEx) and the Lynx X-ray Surveyor.

Juno data shows that some of jupiter’s moons are leaving “footprints” in its aurora

Since it arrived in orbit around Jupiter in July of 2016, the Junomission has been sending back vital information about the gas giant’s atmosphere, magnetic field and weather patterns. With every passing orbit – known as perijoves, which take place every 53 days – the probe has revealed things about Jupiter that scientists will rely on to learn more about its formation and evolution.

Method of making oxygen from water in zero gravity raises hope for long-distance space travel!

Space agencies and private companies already have advanced plans to send humans to Mars in the next few years – ultimately colonizing it. And with a growing number of discoveries of Earth-like planets around nearby stars, long-distance space travel has never seemed more exciting. 

NASA’s Fermi Traces Source of Cosmic Neutrino to Monster Black Hole

NASA’s Fermi Traces Source of Cosmic Neutrino to Monster Black Hole

For the first time ever, scientists using NASA’s Fermi Gamma-ray Space Telescope have found the source of a high-energy neutrino from outside our galaxy. This neutrino traveled 3.7 billion years at almost the speed of light before being detected on Earth. This is farther than any other neutrino whose origin scientists can identify.
