Comments Off on For the first time ever, scientists spotted an object from outside our solar system

Until recently, every asteroid and comet that zipped by Earth came from within our solar system. That just changed, as scientists discovered an object with a trajectory not tied to our Sun. The direction of its approach suggests the asteroid came from Vega, one of the closest stars beyond our Sun. Based on limited observations, astronomers now believe this is the first visitor of its kind to be observed. The preliminary findings were published earlier today by the International Astronomical Union’s Minor Planet Center (MPC) . Said Gareth Williams, the MPC’s associate director, “If further observations confirm the unusual nature of this orbit, this object may be the first clear case of an interstellar comet.” When the object — named A/2017 U1 — entered the solar system , it moved at 26 km (16 miles) per second. At that speed, it could travel 8,200,000,000,000,000 km (more than 850 light years) in 10 million years.

On October 18, however, observers using the PANSTARRS 1 telescope in Hawaii noticed something peculiar about its orbit. After attention was given to the comet, it was later declared to be an asteroid. Reportedly, the PANSTARRS asteroid entered the solar system from the direction of the constellation Lyra. That’s very close to Vega, a star located 25 light years away. If calculations are correct, it took the asteroid nearly 300,000 years to reach Earth . When it passed by our planet on October 14th, it was 24,000,000 km (15,000,000 miles) away. Now, A/2017 U1 is headed out of the solar system, never again to return.

Nissan debuts IMx electric SUV concept with 373-mile driving range

Comments Off on Nissan debuts IMx electric SUV concept with 373-mile driving range

Nissan is getting ready to expand the number of electric vehicles it offers — and the next model will be a Leaf-based electric SUV. Earlier this year Nissan confirmed that an electric SUV is in the works and now we’re seeing our first preview with the debut of the Nissan IMx concept at the Tokyo Motor Show. The IMx concept features a bold exterior that borrows a few styling details from the new 2018 Nissan Leaf, but its suicide doors are purely concept. The IMx concept is based on Nissan’s new EV platform and it has two electric motors , one at the front and one at the rear to give it all-wheel drive capability. While the Nissan Leaf only has a modest 147 horsepower, the IMx concept has 430 horsepower and 516 lb-ft. of torque on tap from its two motors. Related: 2018 Nissan Leaf debuts with 150 mile driving range for just 30k Nissan hasn’t revealed the size of the IMx’s battery pack , but it does have a driving range of over 373 miles, which is pretty much the same driving range you’d get with a typical gasoline powered SUV. Besides the new electric powertrain , the IMx also features a future version of Nissan’s ProPilot autonomous technology. Nissan’s ProPilot system is already arriving on its 2018 models, but the future version in the IMx concept can fully take over control of the vehicle. When ProPilot drive mode is selected, the system stows the steering wheel inside the dashboard and reclines all seats, giving the driver more space and allowing the vehicle’s occupants to relax. When Manual drive mode is selected, the vehicle returns the steering wheel and seats to their original position. The autonomous technology also gives the IMx concept the ability to drive on its own without the driver in the vehicle. The perfect situation? The IMx concept can drop the driver off at a desired destination and then park itself in a nearby parking spot. When the driver is ready to leave, the IMx concept will pick them up. Nissan hasn’t announced when its new electric SUV will be introduced. Images @Nissan + Nissan
