Hi All, I have an unknown 16S ribosomal RNA gene sequence below that I am trying to identify. I know its a bacteria but anyone know of a site/program online that allows you to enter the sequence below and it gives the likely close match? TAGGGAATCTTCCGCAATGGACGAAAGTCTGACGGA...

A galaxy is observed to have a significant redshift in all of its spectral lines. The line normally seen at a wavelength of 327 nm is instead observed at 360 nm. How far is this galaxy from the milkyway My approach All I can calculate here is the red shift based on the formula Z=...

Nobody has yet seen an extraterrestrial, but scientists have found clues that life may be quite common in the universe. So what areas of scientific study are included in the new disciple of "astrobiology"

Hello all, I am studying for an Introductory Astronomy final and I came across an old exam with a few True and False Questions Supermassive black holes are found in the centres of large galaxies (Supermassive is tricky here, not sure on this) Inflation is the name we give to...

Thanks

Hello All, I am studying for my introductory astronomy exam and I came about these two question; Galileo discovered a) radioactivity b) some moons of saturn c) 2 moon of Mars d) some moons of Jupiter e) the telescope I know he discovered 4 moons of Jupiter but "some" is a bit...

I have a very interesting question and is curious to know why: [FONT="Arial Black"]Why do you float 2 m above the bottom of a pool, when you do not float 2m above the ground in air?

try google

I got 0.032 days but this does not seem to be a reasonable value. Besides the equation is 1/synodic period, so I was assuming 1/0.032 =31.25 days

E = Earth sidereal year P = Other planet sidereal year Then sp = 1/(1/E-1/P) using this eq I get 36.7 days. Is this correct?

Would the answer to Vernal equinox be 55 degrees would the answer to summer solstice be 78 degrees Would the answer to winter solstice be 32 degrees

I use the equation u posted 1/Synodic period = 1/Moon sidereal Period - 1/earth's sidereal period = 1/29 -1/365

Thanks for all the hints and help but the exact problem in the text states: If the sidereal period of the moon is 29.0 days(instead of the correct 27.32 days) what would be its synodic period? HINT: consider how far around the sun the Earth & Moon would have traveled in 29.0 days

Lets say for a place that is at a latitude of 55 degrees, how high above the horizon the sun would be on the vernal equinox, summer solstice and winter solstice. Any hints on how to figure this out would be helpful I Know Vernal Equinox-When the sun crosses the Celestial Equator moving...

Does 33.3 days sound right?
