Hah - you don't need any warning to keep your hands away from this spider! This is a female Western Black Widow (Latrodectus hesperus, Theridiidae) spider on her cobweb-like web. I got this photo last May, see this photo from the same day. I don't see these spiders very often, but I know they're out there - a good reason not to stick your hands into dark places. A couple of years ago I found a male of the species which looks quite different - see this photo and this photo. The second of these photos shows that the male also has a red hourglass-shaped mark under the abdomen, but it's not nearly so impressive as the lady's mark. Surely the whole point of that red hourglass is a warning to keep away - even when its not Halloween! Arachtober 31b. (San Marcos Pass, 4 May 2018)
“I cannot promise very much.
I give you the images I know.
Lie still with me and watch.
We laugh and we touch.
I promise you love.
Time will not take that away."
~ Anne Sexton
This celestial object looks like a delicate butterfly. But it is far from serene.
What resemble dainty butterfly wings are actually roiling cauldrons of gas heated to more than 36,000 degrees Fahrenheit. The gas is tearing across space at more than 600,000 miles an hour — fast enough to travel from Earth to the Moon in 24 minutes!
A dying star that was once about five times the mass of the Sun is at the center of this fury. It has ejected its envelope of gases and is now unleashing a stream of ultraviolet radiation that is making the cast-off material glow. This object is an example of a planetary nebula, so-named because many of them have a round appearance resembling that of a planet when viewed through a small telescope.
The Wide Field Camera 3 (WFC3), the newest camera aboard NASA's Hubble Space Telescope, snapped this image of the planetary nebula, cataloged as NGC 6302, but more popularly called the Bug Nebula or the Butterfly Nebula. WFC3 was installed by NASA astronauts in May 2009, during the last servicing mission to upgrade and repair Hubble.
NGC 6302 lies within our Milky Way Galaxy, roughly 3,800 light-years away in the constellation Scorpius. The glowing gas is the star's outer layers, expelled over about 2,200 years. The "butterfly" stretches for more than two light-years, which is about half the distance from the Sun to the nearest star, Alpha Centauri.
The central star itself cannot be seen, because it is hidden within a doughnut-shaped ring of dust, which appears as a dark band pinching the nebula in the center. The thick dust belt constricts the star's outflow, creating the classic "bipolar" or hourglass shape displayed by some planetary nebulae.
The star's surface temperature is estimated to be about 400,000 degrees Fahrenheit, making it one of the hottest known stars in our galaxy. Spectroscopic observations made with ground-based telescopes show that the gas is roughly 36,000 degrees Fahrenheit, which is unusually hot compared to a typical planetary nebula.
The WFC3 image reveals a complex history of ejections from the star. The star first evolved into a huge red-giant star, with a diameter of about 1,000 times that of our Sun. It then lost its extended outer layers. Some of this gas was cast off from its equator at a relatively slow speed, perhaps as low as 20,000 miles an hour, creating the doughnut-shaped ring. Other gas was ejected perpendicular to the ring at higher speeds, producing the elongated "wings" of the butterfly-shaped structure. Later, as the central star heated up, a much faster stellar wind, a stream of charged particles traveling at more than 2 million miles an hour, plowed through the existing wing-shaped structure, further modifying its shape.
The image also shows numerous finger-like projections pointing back to the star, which may mark denser blobs in the outflow that have resisted the pressure from the stellar wind.
The nebula's reddish outer edges are largely due to light emitted by nitrogen, which marks the coolest gas visible in the picture. WFC3 is equipped with a wide variety of filters that isolate light emitted by various chemical elements, allowing astronomers to infer properties of the nebular gas, such as its temperature, density, and composition.
The white-colored regions are areas where light is emitted by sulfur. These are regions where fast-moving gas overtakes and collides with slow-moving gas that left the star at an earlier time, producing shock waves in the gas (the bright white edges on the sides facing the central star). The white blob with the crisp edge at upper right is an example of one of those shock waves.
NGC 6302 was imaged on July 27, 2009, with Hubble's Wide Field Camera 3 in ultraviolet and visible light. Filters that isolate emissions from oxygen, helium, hydrogen, nitrogen, and sulfur from the planetary nebula were used to create this composite image.
These Hubble observations of the planetary nebula NGC 6302 were part of the Hubble Servicing Mission 4 Early Release Observations.

Stitched panorama made with 8 landscape photos, hand held, so I'm a bit amazed there weren't more parallax errors.
I liked how the curved sides looked like the curves in the sand, so I kept them. Not to everyone's taste I suppose.
This is the pano version of this shot which I thought wasn't tall enough.
Want to see it larger, or even larger still? (will open in new tab or window).

I have been quite busy last week. I was in Toronto for 4 days to take care of condo business, and I wasn't feeling well. Still not top shape today...I'm sooo tired and I have no inspiration nor the time to take pictures. I really need some time off. Thank God there's a long weekend coming.
This picture was taken in our Hotel room in Toronto, we had a nice view of the airport and plane coming to land.

Da ma ru - a small hourglass-shaped hand drum. Two cloth-wrapped pellets attached to the drum with string strike the drum heads when the instrument is rotated. The dril bu and da ma ru are played by one player to either reinforce the beats of the cymbals and larger drums, or to play fast, rattling pulsations that intensify the ensemble sound at musical and ritual climaxes.
Dril bu and Rdo rje; the dril bu is a copper alloy handbell with an iron clapper and brass handle, and rdo rje is an hourglass-shaped brass ritual scepter. The dril bu and da ma ru are played by one player to either reinforce the beats of the cymbals and larger drums or to play fast, rattling pulsations that intensify the ensemble sound at musical and ritual climaxes.
Used in Tibetan Buddhist rituals and religious music.
