those of the host planets. the system is an x ray binary, which means that it consists of either a neutron star, which is the remnant of the fairly massive star that underwent a supernova or a black hole. and this compact remnant is in orbit with another star and still has matter, but is not fully involved in the compact object is pulling mass towards itself and as that mass goes towards it and as it falls, it picks up tremendous amounts of energy and begins to emit x rays. this particular system admits a million times as much energy and x ray wavelengths as the sun does across the spectrum. this lanet is sun does across the spectrum. this planet is in sun does across the spectrum. this planet is in orbit sun does across the spectrum. this planet is in orbit with this extreme
we know of 5,000 so called exoplanets those worlds that are orbiting stars beyond our sun but all of them have been located within the milky way galaxy. this saturn sized planet discovered by nasa s chandra x ray telescope is in the messier 51 galaxy. it is 28 million light years away from the milky way. if i told you one light year is 5.8 trillion miles. that s a big bus ride. dr rosanne di stefano is an astrophysicist and one of the resarchers behind the study. this is quite extraordinary. what we know about this planet? know about this planet? welcome eviction summarised know about this planet? welcome eviction summarised the - know about this planet? welcome eviction summarised the main - know about this planet? welcome - eviction summarised the main feature which is that it is most likely size is comparable to the size of saturn. the other thing we know about it is the system that orbits. it s an extraordinary system among all of

this is bbc news. i m christian fraser. another day, another depressing report from the united nations on climate change. we have eight years to halve our greenhouse gas emissions, and commitments made by those gathering in glasgow this week, are a fraction of what is required. it is notjust facebook in the dock tiktok, snapchat and youtube executives were on capitol hill today to answer uncomfortable questions on the type of content they re steering towards young people. speaking of which, youtube today censored more spurious claims by president s bolsonaro of brazil. the senate will vote this next hour on his abject handling of the covid pandemic. and in a galaxy far far away, astronomers have found what could be a planet, the first ever discovered outside our own milky way.
