Edited by Amal Udawatta ,

US President Joe Biden has tested positive for Covid-19 again, in what has been described as a "rebound" infection by his doctor.

The 79-year-old first contracted the virus on 21 July, when he was revealed to be experiencing mild symptoms.

On Saturday Mr Biden said he was not experiencing symptoms but would isolate "for the safety of everyone around me".

The president had tested negative for the virus four times between Tuesday and Friday last week.

In a letter describing the situation, Mr Biden's physician Dr Kevin O'Connor said there was no need to resume treatment but the president would remain under "close observation".

Mr Biden has been taking Paxlovid, an antiviral medicine which Dr O'Connor said had led to a "small percentage" of Covid patients experiencing a "rebound" test.

The longer one extends for 2° in PA 298° and the other 30′ in PA 303°. Details: 11"/ 2.2 RASA and QHY600 camera. Michael Jaeger Amateur astronomers have done it again — discovered a comet. Not by looking through a telescope but through close study of publicly released, low-resolution images taken by the Solar Wind Anisotropies (SWAN) camera on the orbiting Solar and Heliospheric Observatory (SOHO). On March 29th, Vladimir Bezugly of Ukraine was the first to report a moving object in SWAN photos taken the week prior. Michael Mattiazzo of Victoria, Australia, independently found "a pretty obvious comet" the same day using the same images, noting that the object was about 11th magnitude and appeared to be brightening.
