Map of the Universe from Johns Hopkins University and others.....
Johns Hopkins University (JHU) continues to pad its space community résumé with their interactive map, “The map of the observable Universe”,
that takes viewers on a 13.7-billion-year-old tour of the cosmos from the present to the moments after the Big Bang.
While JHU is responsible for creating the site, additional contributions were made by NASA, the European Space Agency,
the National Science Foundation, and the Sloan Foundation.

The First Real Images Of Mercury - What Have We Discovered?
<>
When we look up to the starry sky on a clear night, we get a distant glimpse of seemingly totally alien worlds.
The view to the stars helps us in turn to get an approximate feeling for the relationship of us and our earths
to the great whole. The sheer gigantic universe fascinates us not least because of its countless secrets,
which have posed ever new puzzles to international scientists for many centuries. All the more important
are therefore the groundbreaking new discoveries that are regularly made in the field of astronomical
research. Today: The first real images from mercury surface!

Based on MESSENGER data, a team of geologists believe that (a) a layer of diamond may have been deposited early in Mercury’s history
on top of a molten core, or (b) that diamond crystallized in the cooling core and rose to the core-mantle boundary.

MESSENGER launched from Cape Canaveral Air Force Station on August 3, 2004. It entered orbit around Mercury on March 18, 2011,
the first spacecraft ever to do so. Since then it has performed countless observations of our Solar System�s innermost planet
and has successfully mapped 100% of its surface. Check out the infographic below showing some of the amazing numbers racked up by
MESSENGER since its launch ten years ago
MESSENGER Completes Second Burn to Maintain Mercury Orbit
A little over a week before NASA�s MAVEN spacecraft fired its rockets to successfully enter orbit around Mars,
MESSENGER performed a little burn of its own � the second of four orbit correction maneuvers (OCMs) that will allow
it to remain in orbit around Mercury until next March. Although it is closing in on the end of its operational life
it�s nice to know we still have a few more months of images and discoveries from MESSENGER to look forward to!

Don�t take these spectacular Mercury images (below the jump) for granted.
Three weeks ago, NASA�s orbiting Mercury spacecraft did an engine fire to boost its altitude above the hothouse planet.
Another one is scheduled for January.

The 72-mile (116-km) -wide crater Adedin is seen at an oblique angle in this mosaic made from images
acquired by NASA�s MESSENGER spacecraft. The angle highlights the crater�s central peak complex which surrounds
a shallow depression that could have a volcanic origin, as well as fine cracks in the floor of its basin and a slumped
and terraced section of its far wall. The crater was named after the Bangladeshi painter Zainul Abedin (1914-1976).

Get a Change of View of Mercury�s North Pole
by JASON MAJOR on JANUARY 5, 2015
A forced perspective view of Prokofiev crater near Mercury�s north pole
It�s always good to get a little change of perspective, and with this image we achieve just that:
it�s a view of Mercury�s north pole projected as it might be seen from above a slightly more southerly latitude.
Thanks to the MESSENGER spacecraft, with which this image was originally acquired, as well as the Arecibo Observatory here on Earth,
scientists now know that these polar craters contain large deposits of water ice � which may seem surprising on an airless
and searing-hot planet located so close to the Sun but not when you realize that the interiors of these craters never actually receive sunlight.

The Stunning Highs and Lows of Mercury
Published on May 6, 2016
Data from NASA�s MESSENGER mission have been used to create this animation of the first global digital elevation model (DEM) of Mercury,
revealing in stunning detail the topography across the entire innermost planet and paving the way for scientists to fully characterize its
geologic history. Mercury�s surface is colored according to the topography of the surface, with regions with higher elevations colored brown,
yellow, and red, and regions with lower elevations shown in blue and purple.
The MESSENGER spacecraft was launched on Aug. 3, 2004, and began orbiting Mercury on March 17, 2011.
It spent four years capturing images and information about the planet closest to the sun in unprecedented detail.

Scientists Create Global Topographic Map of Mercury
A team of scientists from NASA, the U.S. Geological Survey, Arizona State University, Carnegie Institute of Washington
and Johns Hopkins University Applied Physics Laboratory has created the first global topographic map of the planet Mercury.
Topographic map of Mercury with labeled features. Mercury�s surface is colored according the topography of the surface,
with regions with higher elevations colored brown, yellow and red, and regions with lower elevations appearing blue and purple.
The highest elevation on the planet is located just south of the equator, and about 2.5 miles above Mercury�s average elevation.
The lowest elevation, which is more than three miles below Mercury�s average, is found on the floor of Rachmaninoff basin,
a basin suspected to host some of the most recent volcanic deposits on the planet.

The planet Mercury, the closet planet to our Sun, is something of an exercise in extremes.
Its days last longer than its years and at any given time, its sun-facing side is scorching
hot while its dark side is freezing cold. It is also one of the least understood planets
in our Solar System. While it is a terrestrial (i.e. rocky) planet like Earth, Venus and Mars,
it has a significantly higher iron-to-rock ratio than the others.
Internal structure of Mercury: 1. Crust: 100�300 km thick 2. Mantle: 600 km thick 3. Core: 1,800 km radius.

Earth’s magnetic poles drift over time. This is something that every airplane pilot or navigator knows.
They have to account for it when they plan their flights.
They drift so much, in fact, that the magnetic poles are in different locations than the geographic poles,
or the axis of Earth’s rotation. Today, Earth’s magnetic north pole is 965 kilometres (600 mi)
away from its geographic pole. Now a new study says the same pole drifting is occurring on Mercury too.
The Earth’s magnetic poles drift around in relation to the geographic poles.
The drift is caused by variations in the flow of the Earth’s liquid core.

Mercury’s magnetic field is dipolar, like Earth’s. It’s powerful enough to slow down
solar radiation and deflect it. But in the past, according to a new study,
it may have been more complicated.

After facing down a couple of delays due to technical difficulties, Europe�s and Japan�s first Mercury orbiter is entering some
of the final stages ahead of its 2016 launch. Part of the BepiColombo orbiter moved into a European testing facility
this past week that will shake, bake and otherwise test the hardware to make sure it�s ready for its extreme mission.

A powerful European Ariane 5 rocket blasted off from French Guiana late Friday(October 20, 2018)
and boosted a pair of satellites into space for a seven-year plunge into the inner solar system,
a voyage requiring seven planetary flybys to slow down enough in the sun�s gravitational clutches
to slip into orbit around hellish Mercury.

BepiColombo consists of two spacecraft that will orbit Mercury. The Mercury Magnetospheric Orbiter (MMO)
follows a larger orbit and investigates the planet’s magnetic field.
The Mercury Planetary Orbiter (MPO) traces a lower orbit and is designed to study the planet itself.

BepiColombo Meets Mercury for the First Time on October 1, 2021
BepiColombo made a quick visit to Venus in August and is on to its next rendezvous.
On October 1st it’ll perform a flyby of Mercury, the spacecraft’s eventual destination.
This visit is just a little flirtation—one of six—ahead of its eventual
orbital link-up with Mercury in late 2025.
When BepiColombo flew past Earth its monitoring cameras were active.
