Updated View of Supernova SN 2016bau in Galaxy NGC 3631
Here is an updated view of the recent supernova in the galaxy NGC 3631 that was discovered by Ron Arbour on March 3, 2016. The view below was taken on April 24, 2016 using a Meade 12” LX-90 telesco…

Here's a view from overhead of the golden James Webb Space Telescope, with its secondary mirror booms stowed. This is the position the secondary mirror will be in during launch. Preparations are being done to rotate the telescope in order to install the flight instrument module behind the primary mirror.

JWST's mirrors are covered in a microscopically thin layer of gold, which optimizes them for reflecting infrared light, which is the primary wavelength of light this telescope will observe.

The Bubble Nebula

NASA's Hubble Space Telescope turned 26 years old last week and astronomers released imagery of an immense bubble being blown into space by a a super-hot, massive star. The stellar wind of hot gases released by the star moves at over four million miles per hour and sweeps up the cold, interstellar gas in front of it, forming the outer edge of the bubble.

The Bubble Nebula is seven light-years across and 7,100 light-years away from the Earth in the constellation Cassiopeia. It was discovered in 1787 by William Herschel, a prominent British astronomer. Hubble's Wide Field Camera-3 imaged the nebula with unprecedented clarity in February 2016 and was used to create this animated flythrough.

A Short Exposure of the Sombrero Galaxy Messier 104 (M104) in Virgo
The Sombrero Galaxy, Messier 104 (M104) is in the constellation Virgo. From my vantage point, it just makes it high enough over the roof of my house to snap a few pictures. The image below was take…

the time it would take for the sun to consume all its hydrogen is about 100 bilion years why is this a unrealistic estimate of the lifetime of the sun

Massive galaxy clusters, can the black hole at their centers change their identities from radio to x-ray's?  Sure!
Galaxy clusters tend to be one of the more interesting objects that I enjoy studying in the astro world. Mainly due to the immense size, gravitational influence and sheer mystery of these objects. Galaxy clusters are the largest objects in the universe held together by gravity, and some of these clusters of galaxies are colliding; thus creating an even larger cluster. That isn't what caught my interest in this cluster however, the Phoenix Cluster...

An image that could change the way astronomers look at "discrepancies" in light distortions in space. The distortions of light around a galaxy nearly 4 billion light-years away is believed to be caused by the gravitational force of an invisible, dark matter galaxy.

NASA’s Spitzer Maps Climate Patterns on a Super-Earth
From NASA: Observations from NASA's Spitzer Space Telescope have led to the first temperature map of a super-Earth planet -- a rocky planet nearly two times as big as ours. The map reveals extreme temperature swings from one side of the planet to the other, and hints that a possible reason for this is the presence of lava flows.

Wouldn't it be more practical to start a terrestrial city on the Moon or Mars before we include the added danger of plummeting 60,000 feet into a 470°c planet?

That is FAST!! I believe its 74,948,112 mps!!!!
Astronomers have observed two black holes in nearby galaxies devouring their companion stars at an extremely high rate, and spitting out matter at a quarter the speed of light.

Since E=mc^2, is there a way to estimate the energy of the system's wind (for some time period) compared to the energy outflow of our sun (for the same time period)?

Perhaps a binary black hole system can slingshot a companion star as a spew of star/gas.  Assume the detected wind is star and/or gas from one average companion star.

scientists are discovering a new like these structures can play a variety of roles in helping microorganisms survive the most hostile environments on Earth, findings that could shed light on how alien life might withstand extreme conditions on distant worlds for more details follow the link

The most complex forms of life on Earth nowadays are eukaryotes, organisms whose cells possess nuclei. However, the first life on Earth were prokaryotes, single-celled microorganisms that do not have nuclei.
                Also  Scientists had discovered a number of prokaryotes that could potentially withstand many of the same extreme conditions found on Mars and other distant planets. A better understanding of how bacteria and archaea survive these dangerous habitats might yield insights into the adaptations that could make life on other worlds possible, said Mechthild Pohlschrode

why does it take so long for the energy of the suns core to reach the surface

why does convection develop about 70% of the way from the sun's center of the surface
suppose the suns nuclear reactions were to drop by 50% next Sunday and resume their normal rate again the following Saturday how noticeable

suppose the density of gas in the suns photosphere fell much less rapidly with increasing distance from the center than it already does what effect would this have on the sharpness of the suns limb

what do we mean when we say that the sun has a temp of 5800k

suppose the suns limb were brighter than the center of the suns disk. what would that tell us about the temperature structure of the suns photosphere

what does the falling of a gas in granules and supergranuels

why do sunspots appear

what is the relationship between coronal holes and solar wind

The Rosette Nebula
View from Tenerife, Canary Islands—a Spanish archipelago located just off the southern coast of Morocco.

The Rosette Nebula (also known as Caldwell 49) is a large, spherical (circular in appearance), H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter. Distance: 5,200 light years  (1,600 parsecs)

Credit: Flickr user Ritzelmut 
Date: April 24, 2016

Technical details: Rosette Nebula with some closeup details, captured 2016-04-22. Parallel exposure of RGB and h-Alpha mono resulting in a HaRGB image. Due to full moon and some high scirrhus clouds there were only possible very short exposure times.

RGB: 160 x 20 sec, Sony A7s (CentralDS modded and colled), ISO 3200, Hyperstar 14", Optolong L-Pro filter
h-Alpha: 36 x 300 sec, Starlight Xpress SX-36 mono, RASA 11", h-Alpha highspeed filter

Both scopes parallel mounted together with an old Zeiss Telemator (for pointing file production due to its incredible tube stability) on a ASA DDM85. Tenerife 1180 m altitude.
