Venus Disappears during Meteor Shower – Early Morning April 22, 2009

(from our friends at OMSI)
On Wednesday morning, April 22 before sunrise (6:25 am PDT), for the Pacific NW viewers, the Moon will completely eclipse brilliant Venus. The event begins just after 5:21 a.m. PDT and lasts until 6:21 am PDT. Both the Moon and Venus will be less than 5 degrees above the eastern horizon for the event. For best viewing (weather permitting), find a good low eastern horizon which is towards Mt Hood for many Portlanders!

In addition, the annual Lyrid meteor shower is underway! Earth is entering a stream of debris from Comet Thatcher, the source of the annual Lyrid meteor shower. Forecasters expect the shower to peak on Wednesday, April 22nd, with a display of 10 to 20 meteors per hour over the northern hemisphere. Occasionally, Earth passes through a dense region of the comet’s tail and rates surge five- to ten-fold. In 1982, for instance, observers were surprised by an outburst of 90 Lyrids per hour. Because Thatcher’s tail has never been mapped in detail, the outbursts are unpredictable and could happen again at any time. The best time to look, no matter where you live, is during the dark hours before dawn on Wednesday morning April 22nd.

As an added bonus, the ISS will be visible at 5:39 am PDT SE moving from SW to ENE and will be just above the Moon and Venus on Wednesday morning. The station will be visible at magnitude of -1.6.

2009 NASA eEducation Electronic Professional Development Network Series

NASA’s Digital Learning Network presents a series of videoconferences to assist educators in staying current on NASA education resources and related products.

During each event, product producers, authors and experts will demonstrate their materials designed to optimize awareness and understanding of science concepts. Instructional objectives, accessing the materials and primary contacts for the materials will also be discussed. During the videoconferences, participants will be able to submit questions to the presenter that will be addressed during the presentation.

The following topics will be covered:

Meteorology: An Educators Resource Guide for Inquiry-Based Learning: April 29, 2009, 4-5 p.m. EST
Meteorology is one of the oldest observational sciences in human history and perhaps the most relevant to a broad segment of society. Learn how the first early meteorologists used this knowledge for their success and survival. This educator guide covers weather patterns, climate and measurement tools.

NASA Explores Virtual Worlds: May 27, 2009, 4-5 p.m. EST
Virtual immersive environments are increasing in popularity in modern America. Explore the virtual world that NASA education is building in Second Life and learn how to become an active citizen of this world.
