Comet C/2007 W1 (Boattini)


Comet C/2007 W1 (Boattini) has brightened enough to see with binoculars and, if you're lucky, with naked eyes.
Comet C/2007 W1 (Boattini) continues to brighten faster than predicted, and has now reached about 6th magnitude. That's bright enough that you can see it without optical aid under excellent conditions, and it should be a relatively easy target through binoculars. The comet currently lies low in the southwestern sky after darkness falls, but it won't stay there long. It can be seen among the background stars of the southern constellation Pyxis the Compass. It lies at about the same altitude at the bright star Procyon in Canis Minor.
The Comet's best view is until the 1st week of June from Southern Hemisphere. Afterwards it will be lost in the glow of the Sun until it emerges in the 1st week of July. Then the Northern Hemisphere population will also have a good look at the comet (hopefully without optical aid). These couple of evenings the sky is not that clear here in Johannesburg, to go comet hunting, but I'm looking for an opportunity to see it soon.

In the 23 May 2008 issue, Science and its online companion Science Signaling explore the stunning diversity and dynamics of the microbial universe. In Science, News stories look at the hidden microbial world inside sponges and ongoing efforts to classify microbes with respect to their environments, while Review articles discuss the microbial processes that drive earth's biogeochemical cycles and approaches to understanding the distribution of microbial taxa and their traits. In Science Signaling, Perspectives explore how different plant pathogens use similar signaling molecules in distinct ways, how gut microbes dampen the host immune response, and how mast cells use extracellular traps to kill microbes.

China's Earthquake: A shattering experience


China's devastating earthquake!

More satellite images have been released portraying the devastation caused by the May 12, 2008 earthquake that struck China's Sichaun Basin. This pair of images, captured by Taiwan’s Formosat-2, illustrates the challenges faced by rescuers bringing equipment and supplies to survivors of the massive 7.9-magnitude earthquake.

Chemspider: Chemical Search Engine

I have found about this product through the Nature issue dated 8/05/08.
This New Chemical Search Engine can be accessed @ http://www.chemspider.com/
According to their web page:
ChemSpider is a free access service providing a structure centric community for chemists. Providing access to millions of chemical structures and integration to a multitude of other online services ChemSpider is the richest single source of structure-based chemistry information.
It has been built with the intention of aggregating and indexing chemical structures and their associated information into a single searchable repository and make it available to everybody, at no charge.
ChemSpider is a value-added offering of publicly available chemical structures since many additional properties have been added to each of the chemical structures. We intend ChemSpider to offer the fastest chemical structure searches available online and delivered with the flexibility and usability necessary to encourage repeat usage. A quick browse of the manual will help understand how ChemSpider can be of value.

With ChemSpider the intention is to aggregate into a single database all chemical structures available within open access and commercial databases and to provide the necessary pointers from the ChemSpider search engine to the information of interest. This service will allow users to either access the data immediately via open access links or have the information necessary to continue their searches into commercially available systems.
ChemSpider was released in March of 2007. At present the database contains information from such diverse sources as a marine natural products database, from all commercially available ACD/Labs databases, from the EPA’s DSSTox efforts and from a series of chemical vendors. The data collections will continue to expand.

Click on ChemRef to search through the following literature sources:
- International Journal of Electrochemical Science
- Association of Clinical Biochemists of India
- Molecular Diversity Preservation International
- PubMed Central
- Hindawi Publishing Corporation
- International Union of Crystallography
- Medknow Publications
- RepositoriUM

Click on Search to have different search options:
- Simple search: Systematic Name, Synonym, Trade Name,Registry Number

World Wide Telescope: New Astronomy Software from Microsoft

WorldWide Telescope (WWT)

Software giant Microsoft is now reaching for the stars with the release of its WorldWide Telescope (WorldWideTelescope.org)
* Want to see the same images that scientists at NASA use for their research or perform your own research with those images?
* Or do you want to see the Earth from the same perspective that astronauts see as they descend to Earth?
WorldWide Telescope is a rich visualization environment that functions as a virtual telescope, bringing together imagery from the best ground- and space-based telescopes to enable seamless exploration of the universe.

Features:
- Exploring the Sky: Within WorldWide Telescope, you can explore deeply into the sky discovering stars, planets, constellations and rich panoramas. You navigate the same way for each — select a view, select the imagery and explore the images in the field of view.
- Zoom and Pan: WorldWide Telescope supports zooming and panning on objects in the sky. As you move through the sky, thumbnails of celestial objects in that constellation display in the navigation pane below the field of view.
- Orientation in the Sky: WorldWide Telescope provides two mechanisms to orient you in the sky. The first is the Sky Ball which represents the field of view with a flat yellow plane. The plane expands and contracts as you zoom into and out of the sky. The other mechanism is the Constellation Overview which represents the size of the field of view in relation to the constellation boundary. You also can orient yourself by selecting your city as the default sky view.
- Collections: WorldWide Telescope includes a rich set of collections of the deep sky objects including constellations, the solar system, images from the Hubble Space Telescope, the Chandra X-Ray Observatory Center, the Spitzer Space Telescope, Sky Surveys, the Messier Catalog, named stars and more.
- Guided tours: A number of expert-created guided tours of the sky, objects in space and collections of celestial objects are built into WorldWide Telescope. Users can create their own tours and share them with others. Slide-based tours are similar to a PowerPoint slide show. Creating tours can be as simple as showing images of deep sky objects or places on the Earth that you have visited. Or it can be as immersive as combining images with art and music to illustrate and enhance your tour. You also can add common license art and music to complement your tour.
- Research the Sky: Using the Finder Scope, it is easy to identify and research objects in the deep sky. The Finder Scope opens a wealth of data and image resources to use when researching the deep sky objects in Set of Identifications, Measurements, and Bibliography for Astronomical Data (SIMBAD), Students for the Exploration and Development of Space (SEDS), Wikipedia, NASA and the Internet.

Read more on: Microsoft Launches Astronomy Software
The first step is to download and install WWT itself from WorldWideTelescope.org. It took me 30 min to download the software, but of course it depends on the speed of the Internet.
For those who enjoyed the night sky, WorldWide Telescope is one more option (remember Google Sky was launched 2 months ago?) to explore the Universe.
