The sheer size and scale of the fires raging in Australia can perhaps best be seen from space.

The big picture: Australia's extreme fires have been made worse by climate change, which exacerbated the country's hot and dry conditions.

Details: Astronauts on the International Space Station caught sight of smoke from the historic fires raging in Australia earlier this month.

  • The station was orbiting 269 miles above the Tasman Sea when this photo was taken on Jan. 4.
  • This season's bushfires in Australia have been far worse than usual, with severe drought and higher-than-normal heat fueling the flames.

WHO: AstraZeneca vaccine must be evaluated on "more than a press release"

Top scientists at the World Health Organization on Friday called for more detailed information on a coronavirus vaccine developed by AstraZeneca and the University of Oxford.

Why it matters: Oxford and AstraZeneca have said the vaccine was 90% effective in people who got a half dose followed by a full dose, and 62% effective in people who got two full doses. AstraZeneca has since acknowledged that the smaller dose received by some participants was the result of an error by a contractor, per the New York Times.

A federal appeals court on Friday unanimously rejected the Trump campaign's emergency appeal seeking to file a new lawsuit against Pennsylvania's election results, writing in a blistering ruling that the campaign's "claims have no merit."

Why it matters: It's another devastating blow to President Trump's sinking efforts to overturn the results of the election. Pennsylvania, which President-elect Joe Biden won by more than 80,000 votes, certified its results last week and is expected to award 20 electoral votes to Biden on Dec. 12.

Longtime Belarusian President Aleksandr Lukashenko has said he will step down after a new constitution comes into force, according to Belarusian state media.

Why it matters: Lukashenko has faced three months of protests following a rigged election in August. He has promised to reform the constitution to reduce the near-absolute powers of the president, but has insisted that his strong hand is needed to see that process through.
