Lindsay Glesenerreplied to: RE: predicting solar storms

Solar storms often start because of a flare/eruption on the Sun. It's extremely challenging to predict when these eruptions are going to happen, so t...

Lindsay Glesenerreplied to: RE: Being a scientist with kids

My career as a scientist tends to take a lot of hours, but there's a lot of flexibility in those hours, much more so than most jobs. As Christina has...

Lindsay Glesenerreplied to: RE: Carrington event today?

We do know how this looks on a smaller scale, because there was a power outage in Quebec in 1989 that was caused by a solar storm. But as the previou...

Lindsay Glesenerreplied to: RE: Science tattoos

I have several tattoos of birds and flowers, but not necessarily science ones. I have seen some very cool science tattos, though - including equation...

Lindsay Glesenerreplied to: RE: new solar cycle?

The Sun's activity goes in an 11-year cycle. During the peak of this cycle, there are usually many sunspots on the Sun and a lot of flares happen. D...

Lindsay Glesenerreplied to: RE: Research on space

No, but I have worked on instruments that went to space for a brief time on rockets, and then came back down to the Earth. (These experiments were pa...

Lindsay Glesenerreplied to: RE: careers

I agree with the previous comments, and I'll also add this - I find competition (even if it's tough!) enjoyable and useful. When I know my colleagues...

Lindsay Glesenerreplied to: RE: upper atmosphere/auroras

The aurora happens because super-fast charged particles sneak into the Earth's atmosphere and collide with ambient atoms and molecules, which release ...

Lindsay Glesenerreplied to: RE: Observing during Solar Eclipses

When the moon blocks out the Sun during an eclipse, it's easier to see the faint corona around the Sun, as Dr. Adams explained. One way to think of i...

Lindsay Glesenerreplied to: RE: solar storm

As you suspected, astronauts that travel between planets would be subjected to much higher doses of radiation than we get here on Earth, and even diff...

Lindsay Glesenerreplied to: RE: Sunspots

Sunspot numbers rise and fall in 11-year cycles. Right now we are in the falling part of the cycle, so there are not very many spots. (To see the Su...

Lindsay Glesenerreplied to: RE: Who inspired you?

I don't think I can pick out one person who inspired me to go into science. I'd say it was the interesting nature of the field of physics itself that...

Lindsay Glesenerreplied to: RE: Eclipse August on 21st

I also saw the eclipse from Salem, and it was very cool to observe the sky dimming, the air temperature decrease, and the moon's shadow overtake the s...

Lindsay Glesenerreplied to: RE: sunspot

I'm not sure what the largest sunspot is, but an extremely large one showed up on the Sun just a couple years ago. This one was visible on the Sun in...

Lindsay Glesenerreplied to: RE: Size of sunspots

Sunspots are caused by the Sun's magnetic field, a complicated, churning field that is always evolving. Some of the changes are slow, like gradual su...

Lindsay Glesenerreplied to: RE: Your Career

Yes, I believe I will still be studying the Sun. There's so much that can be learned from studying our nearest star, and we still have a lot to learn...

Lindsay Glesenerreplied to: RE: Planet Names

In English (and in the Romance languages) the planets are named after Roman and Greek gods. This came from ancient times, as the planets were very im...
