Zero Shadow Day, the day on which the sun is directly overhead at local noon.
For Chennai, India at 13°N it was on 24th Apr 12:07PM. The sun reaching 89.6°altitude.
Interesting fact : This event happens only for locations between 23.5°N to 23.5°S latitudes, which leaves out the entire continental unites states and Europe.

The image was captured by my DIY all sky camera setup. Powered with a Rasperry Pi HQ camera / fisheye lens combo. North is left and West is top in the image.

Looked at the conjunction this morning and saw the oddest clouds. Shot with a Pixel 3 in Hartford, AL, USA
This appears to be the launch of NASA's Crew 4 Mission on SpaceX Falcon 9.

I got up early this morning to take some pictures of the planetary conjunction and I was treated with two nice surprises:

1) In addition to Jupiter, Venus, Mars, Saturn and the Moon, Neptune is (barely) visible in some images!

But the real treat is that 2) The contrail from the Falcon 9 launch was still visible (2 hours after launch) and made these beautiful "clouds" in the direction of the planets.

Melotte 15

https://flic.kr/p/2nhiw5g

Copyright Mark Hoffman

From NASA:
"Cosmic clouds form fantastic shapes in the central regions of emission nebula IC 1805. The clouds are sculpted by stellar winds and radiation from massive hot stars in the nebula's newborn star cluster, Melotte 15. About 1.5 million years young, the cluster stars are scattered in this colorful skyscape, along with dark dust clouds in silhouette against glowing atomic gas. A composite of narrowband and broadband telescopic images, the view spans about 15 light-years and includes emission from ionized hydrogen, sulfur, and oxygen atoms mapped to green, red, and blue hues in the popular Hubble Palette. Wider field images reveal that IC 1805's simpler, overall outline suggests its popular name - The Heart Nebula. IC 1805 is located about 7,500 light years away toward the boastful constellation Cassiopeia."

PLANETARY PARADE!
I took a detour on my way to work this morning to grab a picture of the crescent moon rising above Alcatraz, with Jupiter, Venus, Mars, and finally, Saturn gracefully posing above the cables of the north tower of the Golden Gate Bridge. Taken from Battery Spencer in the Marin Headlands. IA spectacular sunrise followed.

NGC 4565 (also known as C 38 or the Ago Galaxy) is a spiral galaxy in the Coma Berenices constellation. It is easily identified 2.5 degrees southeast of the star γ Comae Berenices; it is perfectly cut, so it looks like a long spindle. Visible even with modest instruments, in 200mm aperture telescopes the view is wonderful: for the entire length of the galaxy a dark band is clearly evident, in a slightly asymmetrical position with respect to the nucleus, which makes it extraordinarily similar to our Galaxy, to which on the other hand it approaches both in real form and in size. It is about 52 million light-years away from the Milky Way. Distance from Earth: 38,490,000 light years

A year of the Sun by Salvatore Cerruto, su Flickr

I was curious to experience and touch how the path of the Sun changed during the year and here on April 4th of this year I take the camera left on the roof of my house after a very long wait. As soon as I extracted the film from the pinhole camera I observed something really unusual, almost bizarre. In human experience it is difficult to imagine an overall representation of the movement of the celestial bodies and stars over a very long time and with this experimentation it is immediately clear how during the span of a year the trajectory of the Sun changes so much both in amplitude and in declination. The lower trajectory in fact represents the winter solstice and the higher trajectories represent the approach to the summer solstice which would correspond to the highest arc which unfortunately is not shown in this photo. At the same time as the sun reaches an ever greater declination it rises more and more in the east and sets more and more in the west, thus increasing its amplitude as summer approaches and, decreasing it as winter approaches. As I mentioned, to make this photo I used a pinhole camera which, in my case, is nothing more than a simple can with a very small hole and a photographic film inside.
