schwit1 writes: Astronomers have discovered several new objects orbiting the Sun at extremely great distances beyond the orbit of Neptune. The most interesting new discovery is 2014 FE72: “2014 FE72 is the first distant Oort Cloud object found with an orbit entirely beyond Neptune,” reports Carnegie Institution for Science. “It has an orbit that takes the object so far away from the Sun (some 3000 times farther than Earth) that it is likely being influenced by forces of gravity from beyond our Solar System such as other stars and the galactic tide. It is the first object observed at such a large distance.” This research is being done as part of an effort to discover a very large planet, possibly as much as 15 times the mass of Earth, that the scientists have proposed that exists out there.

SETI Has Observed a ‘Strong’ Signal That May Originate From a Sun-like Star

An anonymous reader writes: The RATAN-600 radio telescope in Zelenchukskaya, Russia has detected a strong signal around 11 GHz (which is very unlikely to be naturally-caused) coming from HD164595, a star nearly identical in mass to the Sun and located …

An anonymous reader writes: The RATAN-600 radio telescope in Zelenchukskaya, Russia has detected a strong signal around 11 GHz (which is very unlikely to be naturally-caused) coming from HD164595, a star nearly identical in mass to the Sun and located about 95 light years from Earth. The system is known to have at least one planet. If the signal were isotropic, it would seem to indicate a Kardashev Type II civilization. While it is too early to draw any conclusions, the discovery will be discussed at an upcoming SETI committee meeting on September 27th. According to Paul Gilster, author of the Centauri Dreams website, “No one is claiming that this is the work of an extraterrestrial civilization, but it is certainly worth further study. Working out the strength of the signal, the researchers say that if it came from an isotropic beacon, it would be of a power possible only for a Kardashev Type II civilization. If it were a narrow beam signal focused on our Solar System, it would be of a power available to a Kardashev Type I civilization. The possibility of noise of one form or another cannot be ruled out, and researchers in Paris led by Jean Schneider are considering the possible microlensing of a background source by HD164595. But the signal is provocative enough that the RATAN-600 researchers are calling for permanent monitoring of this target.”

India has become the fourth country to demonstrate the flight testing of scramjet engine after the US, Russia and European Space Agency. According to a report, the scramjet will bring down the launch cost of weather satellite INSAT-3DR which is a weather forecast system designed for enhanced meteorological observations and disaster warning. The satellite scheduled to be launched in August earlier, but it has been postponed to September.

NASA lost contact with its STEREO-B spacecraft twenty-two months ago during a routine 72-hour test. On Sunday, the spacecraft reconnected with NASA roughly 189 million miles away from Earth. While that would seem like a cause for celebration, “the very hard and scary work is just the beginning, says Stereo project scientist Joe Gurman, as the agency has to turn on the computer to learn more about the current state of the spacecraft — a process that may make the craft lose contact with them again. Slashdot user bongey writes: NASA may have only two minutes or less to fix a STEREO-B satellite before the computer causes it to lose contact again. NASA lost contact with their STEREO-B satellite nearly twenty-two months ago when performing a routine test. NASA scientists are afraid to turn on the computer at this point because it may cause them to lose contact again. A more detailed technical summary can be found here. “We have something like two minutes between when STEREO-B receives the command to boot up one of its computers and when it starts doing what we don’t want it to do,” Gurman said. Business Insider writes, “Making matters worse, it takes about 20 seconds to send commands to the spacecraft — a data rate that makes a dial-up modem seem lightning fast.”
