Transit of Venus on June 5th, 2012

Story

If you visit the Public Observatory during its daytime hours in May (1–3pm on Wednesday through Saturday, weather permitting), you can use the 16” telescope to observe an object which looks a lot like the Moon.  Hanging in a blue sky, it shines with yellowish reflected sunlight.

Shedding Light on a Common Problem

Story

If you've been to any of the nighttime observing sessions at our Public Observatory, you might have wondered why we mostly view the planets and the Moon. After all, the Observatory houses a professional 16-inch telescope, and several other high-quality portable telescopes; shouldn't they be able to show us great views of galaxies or nebulas?   They should, and they could, if they were located at what astronomers call a "dark site" — away from the city lights that often outshine the lovely stars of nighttime.

Mapping Everything

Story

The universe is about 13.7 billion years old and has expanded since its beginning at the Big Bang. Because distant objects appear to be receding as the universe expands, the light from them is “stretched” out, altering its wavelength to the red part of the electromagnetic spectrum. This “redshift” can be measured for every object in deep space.

Astronomy Night at the Museum

Story

The night opened with few clouds and a bright waxing gibbous moon. Alex and I, interns at the National Air and Space Museum, stood outside with Sean O'Brien, astronomy educator at the Museum and Albert Einstein Planetarium technician, to survey the sky and anticipate the night. This was my first star party at the Museum. As we set up, the first line of visitors formed outside the door of the Public Observatory waiting for 6 p.m. — opening time. We set up the Tele Vue telescope first. The view was spectacular. Along the terminator, the line between the dark and light sides of the Moon, craters popped between the stark white of the moon and the blue of the sky.

Jumping In Tweet First

Story

On Saturday, March 19, I was thrilled to participate in the first ever Sun-Earth Day Tweetup organized by the NASA Goddard Spaceflight Center. It was also the first time the Smithsonian officially participated in a Tweetup. The event was a great opportunity to give twitter fans (aka “tweeps”) some face-to-face interaction with our research scientists, curators and educators, and provide some fun hands-on learning that illustrated the Sun-Earth connection.
