An
extraterrestrial spacecraft lurking in a satellite’s orbit nearby Earth would
be able to see city lights and pollution in our atmosphere. But what if it
searched for signs of life on Earth from afar? This question has great
pertinence to those searching for other Earths outside of our solar system.
NASA’s Keppler space telescope is among a fleet of telescopes and spacecraft
searching for rocky planets alike to our own. Once the size and location of
these worlds are plotted, the next step is examining the chemical composition
of their atmospheres.

Stunning Photographs of Colorful Hummingbirds
Hummingbirds are famous for flapping their wings
exceptionally fast that they create a distinct hum and appear as a blur of
feathers right before your eyes. To look over the beauty of such a miniature
creature is near impossible when the birds are zipping rapidly through the air.
Scotland photographer Chris Morgan demonstrated
an incredible thirst for depicting the unique birds through his lens, during
his trip to Costa Rica. To captivating hummingbirds, a lot of patience to be required,
and Morgan did the job extremely well by capturing dazzling photos of many
hummingbirds from quite close up.
Morgan photographs feature the astonishingly
sharp details of eyes, beaks, and layers of bright, iridescent feathers and
viewers can actually stare directly into the large, shiny black eye of a single
bird.
Morgan said; the hummingbirds are normally so
tempting to photograph to the point of madness and it took a while to be able
to get any shots of one. In the space of an hour I took nearly a thousand of
photographs. A good proportion was excellent out of focus pictures of bushes
with no birds to be seen but i really felt my abilities improved over the hour,
and nothing like a bit of practice. Check out Christ Roger on Flickr

Bonsai Japanese Red Maple
Bonsai Japanese Red Maple
Originally, the term Bonsai simply meant "a plant grown in a
container". Nowadays, Bonsai means "miniaturized plant, shrub, or
tree in a planter". This miniaturization process is accomplished by
planting in a smaller than normal container and by sensible pruning to make the
plant resemble its larger counterpart in nature.

The Sweet Kip Kip Wheep Wheep Squirrel Cuckoo
The squirrel cuckoo (Piaya
cayana) is a large and active species of cuckoo. It can be found in wooded
habitats from northwestern Mexico to northern Argentina and Uruguay, and on
Trinidad. The large cuckoo is extremely long-tailed about 40.5–50 centimeters
long and weighs 95 to 120 grams. It is common and is most often seen in gliding
from one tree to another, or enthusiastically hopping from branch to branch in
hunt of a wide variety of arthropods. The adult cuckoo has mainly chestnut upper-parts
and head, becoming paler on the throat. The lower breast is grey and the belly
is blackish. The central tail feathers are Rufous, but the outer are black with
white tips. The bill is yellow and the iris is red. Immature birds have a grey
bill and eyeing, brown iris, and less white in the tail.
It looks like the little cuckoo,
but that species is smaller and has a darker throat. However unique throughout
its range it is highly polytypic with fourteen subspecies that vary in the
coloration of their under-parts, throat, bare parts, and tail. Therefore; few
of these subspecies are quite different, and due to their lack of integration
with adjoining subspecies maybe represent separate species. The Squirrel Cuckoo
is a common species that inhabits a diversity of forested habitats across its
range, including humid to semi humid forest, deciduous forest, forest edge,
second growth, plantations, and even scattered trees in open country.
There’re a number of subspecies
with minor plumage variations. i.e P. c. mehleri, one of the South American
subspecies, has mainly brown outer tail feathers. Moreover, the subspecies from
Mexico, Central America, and northern and western South America have a yellow
eye-ring, but this is red in the remaining part of South America. It is
explosive kip! kip! weeuu calls, and the song is a whistled wheep wheep wheep
wheep wheep. Nests are constructed in trees or in low dense growth. Although
building, one partner male brings material to the other, who stays on the nest
and arranges it. The completed nest comprises of a loose foundation of coarse
sticks supporting a thick mass of leaves, some of which are green when brought
back. The clutch typically is two egg which are chalky white and unmarked; the
eggs may become stained brown by the leaves in the nest. Source: Charismatic Planet
