More and more Taiwanese people are reading news on Facebook instead of watching TV or newspapers. Issues like typhoon disasters or environmental issues may receive more attention as a result. Astronomers have discovered the first aurora seen beyond our solar system, which is 10,000 times more powerful than any previously seen. It was found not from a planet but from a low-mass star between stars and brown dwarfs. This indicates that auroral activity replaces solar-like coronal activity on brown dwarfs and smaller objects. The combination of radio and optical observations showed the object, 18 light-years from Earth, has characteristics unlike more-massive stars. Brown dwarfs are objects more massive than planets yet too small to trigger nuclear

Astronomers have discovered the first aurora ever seen in an object beyond our solar
system. The aurora — similar to the famous “Northern Lights” on Earth — is 10,000 times
____ powerful ____ any previously seen. They found the aurora not from a planet, but from
a low-mass star at the boundary between stars and brown dwarfs.
1. ___ (a) such…as… (b) so…that… (c) more…than… (d) as…as…
“All the magnetic activity we see on this object can be explained by powerful auroras,” said
Gregg Hallinan of the California Institute of Technology. “This ______ that auroral activity
replaces solar-like coronal activity on brown dwarfs and smaller objects,” he said.
2. ___ (a) indicates (b) communicates (c) transfers (d) calls
The astronomers observed the object, called LSR J1835+3259, using the Karl G. Jansky
Very Large Array (VLA) at radio wavelengths, along with the 5-meter Hale Telescope on
Palomar Mountain and the 10-meter Keck Telescope in Hawaii at optical wavelengths. The
combination of radio and optical ______ showed that the object, 18 light-years from Earth,
has characteristics unlike any seen in more-massive stars.
3. ___ (a) procedures (b) glimpses (c) telescopes (d) observations
Brown dwarfs, sometimes called “failed stars,” are objects more massive than planets,
＿＿＿ too small to trigger the thermonuclear reactions at their cores that power stars. The
astronomers said their observations of LSR J1835+3259 indicate that the coolest stars and
brown dwarfs have outer atmospheres that support auroral activity, rather than the type of
magnetic activity seen on more-massive and hotter stars.
4. ___ (a) and (b) yet (c) thus (d) instead
