Professor Zaza, University of Georgia, hase extended the idea of Freeman Dyson and has shown that a supercivilization has to use ring-like megastructures around pulsars instead of a spherical shell. He reexamined the same problem in the observational context and he shows that facilities of modern IR telescopes (VLTI and WISE) might efficiently monitor the …
Currently there are 3486 confirmed exoplanets (mainly from the Kepler Space telescope survey) and there are 4496 exoplanet candidates and 581 multiplanet systems. We are within about 11 months of the launch of the TESS space telescope. The Transiting Exoplanet Survey Satellite (TESS) will discover thousands of exoplanets in orbit around the brightest stars in …
SpaceX said it plans to launch thousands of satellites on Falcon 9 rockets beginning in 2019 to establish what would one day become a global broadband internet constellation. Patricia Cooper, SpaceX’s vice president of satellite government affairs, told the Senate Committee on Commerce, Science and Transportation that the company is aiming to launch 4,425 small …
SpaceX is on track for a Monday evening (May 15, 2017) launch of an Inmarsat-5 communications satellite. If the launch is successful then it would be the sixth Spacex launch in four months. Spacex could launch again at the beginning of June a cargo supply mission to the International Space Station. SpaceX could be on …
The Carnival of Space 508 is up at The Evolving Planet Universe Today – Only 10 Light-Years Away, there’s a Baby Version of the Solar System Astronomers are understandanly fascinated with the Epsilon Eridani system. For one, this star system is in close proximity to our own, at a distance of about 10.5 light years …
SpaceX’s second re-launch of a previously used Falcon 9 rocket booster is targeted for next month, for a mission launching a Bulgarian communications satellite from Kennedy Space Center. The turnaround time between missions will be significantly shorter — five months instead of 12, if a mid-June target date holds. Maxim Zayakov, CEO of Bulsatcom and …
SpaceX successfully landed its Falcon 9 rocket on solid ground again, after launching the vehicle from Cape Canaveral, Florida. The rocket stage landed at Spacex Landing Zone 1 which is located just off the coast of the Cape. It’s the fourth time SpaceX has landed one of its rockets on land, and the 10th time …
A paper suggests that habitable zone waterworlds like Earth would usually have no land or very little land. This would be another factor that would make technological civilizations more rare. On a purely statistical basis, one naïvely expects to find a highly asymmetric division of land and ocean surface areas. A natural explanation for the …
