HST images 3 sections
of the Veil Nebula which is the shattered remains of a supernova that exploded
thousands of years ago. The images provide beautiful views of the delicate, wispy
structure resulting from this cosmic explosion.

Evidence for Type Ia
Supernovae Scenario Observations
obtained with ESO's VLT, has allowed astronomers to find direct evidence for the material
that surrounded a star before it exploded as a Type Ia supernova.

HST images of Vesta
and Ceres
Two of the most massive asteroids in the asteroid belt, a region between Mars and Jupiter.
On July 7, NASA is scheduled to launch the spacecraft on a four-year journey to the
asteroid belt. Once there, Dawn will do some asteroid-hopping, going into orbit around
Vesta in 2011 and Ceres in 2015. Dawn will be the first spacecraft to orbit two targets.

Gamma-ray burst
velocity measured Using a
robotic telescope at the ESO La Silla Observatory, astronomers have for the first time
measured the velocity of the explosions known as gamma-ray bursts. The material is
travelling at the extraordinary speed of more than 99.999% of the velocity of light, the
maximum speed limit in the Universe.

Ring of Dark Matter
Astronomers using the HST have discovered a ghostly ring of dark matter that formed long
ago during a titanic collision between two massive galaxy clusters. The ring's discovery
is among the strongest evidence yet that dark matter exists. Astronomers have long
suspected the existence of the invisible substance as the source of additional gravity
that holds together galaxy clusters.

Astronomers Find First
Earth-like Planet in Habitable Zone
Astronomers have discovered the most Earth-like planet outside our Solar System to date,
an exoplanet with a radius only 50% larger than the Earth and capable of having liquid
water.

The Purple Rose of
Virgo
Until now NGC 5584 was just a galaxy among many others to the West of the Virgo Cluster.
Known only as a number in galaxy surveys, its beauty is now revealed in a new VLT image.
Since 1 March, this purple cosmic rose also holds the brightest stellar explosion of the
year, known as SN 2007af. About 75 million light years away towards the constellation
Virgo it is slightly smaller than the Milky Way but belongs to the same category being
barred spirals.

New Globular Cluster
Found in Milky Way
Images made with ESO's New Technology Telescope at La Silla by a team of German
astronomers reveal a rich circular cluster of stars in the inner parts of our Galaxy.
Located 30,000 light-years away, this previously unknown closely-packed group of about
100,000 stars is most likely a new globular cluster.

The combined ultraviolet- and
visible-light images of Jupiter seen here from the Hubble Space Telescope were taken on
February 17-21. The image segments in the boxes, obtained using the Advanced Camera for
Surveys's ultraviolet camera, show auroral emissions that are always present in Jupiter's
polar regions. The equatorial regions of Jupiter were imaged in blue light by the Wide
Field Planetary Camera 2. Cloud features in Jupiter's main atmosphere are revealed. In the
ultraviolet views, the atmosphere looks more hazy because sunlight is reflected from
higher in the atmosphere.

Observations of SN
1987A, made over the past 20 years by NASA’s Hubble Space Telescope and many
other major ground- and space-based telescopes, have significantly changed astronomers'
views of how massive stars end their lives. Astronomers credit Hubble's sharp vision with
yielding important clues about the massive star's demise.

HST reveals colourful
destruction of a Sun-like star ending its life by casting off outer layers of
gas, which form a cocoon around the star's remaining core. Ultraviolet light from the
dying star makes this material glow. The burned-out star, (now a white dwarf), appears as
a white dot at the center. The Milky Way Galaxy is littered with these stellar relics,
called planetary nebulae. Hubble's Wide Field Planetary Camera 2 captured this image of
planetary nebula NGC 2440 on February 6th 2007.

C/2006 P1 McNaught -
What a beautiful sight 19th Jan 2007
like most we've followed the passage of Comet C/2006 P1 which has put on an awesome
display over the last week. Steve Quirk of Mudgee NSW has managed some terrific images
from favorable dark skies using our GSTAR-EX camera.

Trio of Quasars
Astronomers have discovered what appears to be the first known triplet of quasars. This
close trio of supermassive black holes lies about 10.5 billion light-years away towards
the Virgo (The Virgin) constellation.

A blizzard of particles in a
disk around a young star reveals the process by which planets grow from tiny dust grains.
The particles are as fluffy as snowflakes and are roughly ten times larger than typical
interstellar dust grains. They were detected in a disk encircling the 12-million-year-old
star AU Microscopii by the HST. The star is 32 light-years away in the southern
constellation of Microscopium.

Swirls of gas and dust seen in
this ethereal-looking region of star formation. This majestic view of LH 95, located in
the Large Magellanic Cloud, reveals a region where low-mass, infant stars and their much
more massive stellar neighbors reside. A shroud of blue haze gently lingers amid the
stars. Image taken in March 2006 with Hubble's Advanced Camera for Surveys.

A captivating image of the
starburst galaxy NGC 1313, taken with the FORS instrument using the VLT, reveals its inner
turmoil. The dense clustering of bright stars and gas in its arms, a sign of an ongoing
boom of star births, shows a mere glimpse of the rough times it has seen. Probing ever
deeper into the heart of the galaxy, astronomers have revealed many enigmas that continue
to defy our understanding.

First Directly Imaged
Brown Dwarf Companion to an Exoplanet Host Star Astronomers have detected a new faint companion to the star HD
3651, already known to host a planet. This companion, a brown dwarf, is the faintest known
companion of an exoplanet host star imaged directly and one of the faintest T dwarfs
detected in the Solar neighbourhood so far. The detection yields important information on
the conditions under which planets form.

Dwarf Planet Eris
imaged with GSTAR-EX
In yet another first for video, Steve Quirk of Mudgee in NSW successfully managed to image
the dwarf planet Eris (2003 UB313) over 3 days. The distance to Eris is about 97 AU being
nearly 3 times more distant than Pluto. Even more impressive and further vindication of
just how well our GSTAR-EX cameras perform, he managed this under bright skies with a 9 to
11 day old Moon high in the sky at the time.

Using the VLT Interferometer,
astronomers have solved a 140-year-old mystery concerning active hot stars. They indeed
show that the star Alpha Arae is spinning almost on the verge of breaking and that its
disc rotates the same way planets do around the Sun.
