NASA's Voyager 2 Probe could be Nearing Interstellar Space

NASA's Voyager 2 probe, currently on a journey toward interstellar space, has detected an increase in cosmic rays that originate outside our solar system. Launched in 1977, Voyager 2 is a little more than 11 billion miles (about 17.8 billion kilometers) from Earth, or more than 118 times the distance from Earth to the Sun.

Since 2007 the probe has been traveling through the outermost layer of the heliosphere—the vast bubble around the Sun and the planets dominated by solar material and magnetic fields. Voyager scientists have been watching for the spacecraft to reach the outer boundary of the heliosphere, known as the heliopause. Once Voyager 2 exits the heliosphere, it will become the second human-made object, after Voyager 1, to enter interstellar space.

Since late August, the Cosmic Ray Subsystem instrument on Voyager 2 has measured about a 5 percent increase in the rate of cosmic rays hitting the spacecraft compared to early August. The probe's Low-Energy Charged Particle instrument has detected a similar increase in higher-energy cosmic rays.

Cosmic rays are fast-moving particles that originate outside the solar system. Some of these cosmic rays are blocked by the heliosphere, so mission planners expect that Voyager 2 will measure an increase in the rate of cosmic rays as it approaches and crosses the boundary of the heliosphere.

Betelgeuse is Getting Ready to Go Supernova

The red supergiant star Betelgeuse is getting ready to go supernova, and when it does Earth will have a front-row seat. The explosion will be so bright that Earth will briefly seem to have two suns in the sky.

The star is located in the Orion constellation, about 640 light-years away from Earth. It's one of the brightest and biggest stars in our galactic neighborhood - if you dropped it in our Solar System, it would extend all the way out to Jupiter, leaving Earth completely engulfed.

Someday soon (astronomically speaking), it will run out of fuel, collapse under its own weight, and then rebound in a spectacular supernova explosion. When this happens, Betelgeuse will brighten enormously for a few weeks or months, perhaps as bright as the full moon and visible in broad daylight.

When will it happen? Probably not in our lifetimes. But, in fact, no one really knows. It could be tomorrow or a million years in the future.

The "desierto florido" (flowering desert) phenomenon usually occurs every five to seven years when rains cause buried seeds to germinate and flower. More than 200 species of plant have been found to grow in the area. The spectacle draws visitors and botanists from Chile and further afield.

Xiaomi wants to take the UK by storm in November before finally reaching the US - Xiaomi, once dubbed the “Apple of China”, has impressively managed to defy the global smartphone market stagnation of the past couple of years, rapidly growing not just in its homeland, but India and various major European countries as well. Of course, the US is an entirely different animal, but even though trade tensions between the two massive economies are still mounting, the company remains focused on buil...

Spectacular Gamma-Ray Pulsar Glows in the Outskirts of the Tarantula Nebula

Researchers using NASA's Fermi Gamma-ray Space Telescope have discovered the first gamma-ray pulsar in a galaxy other than our own. The object sets a new record for the most luminous gamma-ray pulsar known.

The pulsar lies in the outskirts of the Tarantula Nebula in the Large Magellanic Cloud, a small galaxy that orbits our Milky Way and is located 163,000 light-years away. The Tarantula Nebula is the largest, most active and most complex star-formation region in our galactic neighborhood. It was identified as a bright source of gamma rays, the highest-energy form of light, early in the Fermi mission. Astronomers initially attributed this glow to collisions of subatomic particles accelerated in the shock waves produced by supernova .

However, the discovery of gamma-ray pulses from a previously known pulsar named PSR J0540-6919 shows that it is responsible for roughly half of the gamma-ray brightness previously thought to come from the nebula.

Gamma-ray pulses from J0540-6919 have 20 times the intensity of the previous record-holder, the pulsar in the famous Crab Nebula. Yet they have roughly similar levels of radio, optical and X-ray emission. Accounting for these differences will guide astronomers to a better understanding of the extreme physics at work in young pulsars.
