Venus was once considered a twin to Earth, as itís roughly the same size and is relatively close to our planet.
But once astronomers looked at it seriously in the past half-century or so, a lot of contrasts emerged. The biggest one ó
Venus is actually a hothouse planet with a runaway greenhouse effect, making it inhospitable to life as we know it.

As the morning star, the evening star, and the brightest natural object in the sky (after the Moon),
human beings have been aware of Venus since time immemorial. Even though it would be many thousands of years
before it was recognized as being a planet, its has been a part of human culture since the beginning of recorded history.

NASA SDO - Venus and Coronal Loops

Published on Jun 5, 2012 As we are almost halfway through the Venus Transit, here is a look at Venus through the NASA Solar Dynamics Observatory AIA instrument.
This is in 171 angstrom wavelength. This channel is especially good at showing coronal loops - the arcs extending off of the Sun where plasma moves along magnetic field lines.
The brightest spots seen here are locations where the magnetic field near the surface is exceptionally strong.

A movie of the Venus' night-side produced by IR2

This movie is produced from the IR2 2.26-Ķm images, acquired on 29 March 2016 at a distance of 0.36 million km.
Original 4 images were acquired with 4-hour intervals from 16:03 JST (07:03 UT). In 4 hours, the super-rotating clouds move by ~10 degrees. Such images are numerically derotated to produce
intermediate images so that the resultant motion becomes smoother.
Deformation, appearance and disapperance of clouds are obvious in this movie.

at an altitude of around 130 kilometres from 18 June to 11 July 2014. In the month before,
the altitude was gradually reduced from around 200 to 130 kilometres.

The 58 images comprising the movie were obtained by the Venus Monitoring Camera instrument in ultraviolet light.

Published on Feb 23, 2013 A quick and dirty animation of images obtained by the Venus Express spacecraft. The images were obtained during orbit 1749
(one of the the so-≠-called "VEX Terminator Observations").

Venus Express May Be Out Of Fuel After Death-Duelling Maneuvers

After more than eight years orbiting a hellish planet, Venus Express is showing its age.
The spacecraft made some risky maneuvers this summer, dipping down into the atmosphere as it nears the end of its mission.
Now, the European Space Agency reports it has mostly lost contact with the probe. The reason could be lack of fuel.

After surviving an eight-year mission and a daring plunge into part of the atmosphere of Venus,
a plucky spacecraft orbiting the hothouse planet is finished its mission, the European Space Agency declared.
Venus Express can no longer communicate consistently with Earth

Exploring Venus By Airship: Cool Concept, But Certainly Not New
by Elizabeth Howell on December 22, 2014

Venus presents a special challenge to space explorers. Yes, there is a surface, but hellish temperatures
and atmospheric pressure on the surface of Venus has a tendency to crush spacecraft fairly quickly.
Short of building a submarine-rated surface explorer, maybe thereís a better way to look at the hothouse planet?
A newly proposed NASA concept suggests using airships. Yes, airships with people in them.

Because of its proximity to Earth, and its similarity in size, mass and composition, Venus was once believed to hold life.
In fact, the idea of Venus being a tropical world persisted well into the 20th century, until the Venera and Mariner programs
demonstrated the absolute hellish conditions that actually exist on the surface.

Venus Plane Pushed for Next NASA Next Frontiers Mission
by Dan Leone, Space News Writer | May 12, 2015 11:06am ET

Northrop Grumman has come up with a Venus mission concept called VAMP (Venus Atmospheric Maneuverable Platform):
An inflatable propeller plane that could cruise Earth's super-heated sister planet for years,
SAMPLING the acidic alien atmopshere directly and safely observing the venusian surface from 50 kilometers up.

Japanís Akatsuki Spacecraft to Make Second Attempt to Enter Orbit of Venus in December 2015

Back in 2010, the Japanese Aerospace Exploration Agency (JAXA) launched the The Venus Climate Orbiter ďAkatsukiĒ
with the intention of learning more about the planetís weather and surface conditions. Unfortunately, due to engine trouble,
the probe failed to make it into the planetís orbit. Since that time, it has remained in a heliocentric orbit, some 134 million kilometers from Venus,
conducting scientific studies on the solar wind. However, JAXA is going to make one more attempt to slip the probe into Venusí
orbit before its fuel runs out.
UPDATE DECEMBER 17, 2015 Japanese probe fires rockets to steer into orbit at Venus Posted on 7 December 2015 by Stephen Clark Five years after missing a shot to enter orbit at Venus, Japanís Akatsuki spacecraft completed a critical rocket burn early Monday, Dec 7, 2015
in a bid to salvage the research mission and become the only space probe operating around Earthís nearest planetary neighbor.
Four maneuvering thrusters were scheduled to ignite at 2351 GMT (6:51 p.m. EST) Sunday for approximately 20 minutes and 30 seconds
to slow down the Akatsuki probe enough for Venusí gravity to capture it into an elongated, high-altitude orbit.
