Astronomers first observed dark galaxies in the early universe

The astronomers made a series of very long exposures to detect the weak fluorescent glow of dark galaxies.

The team managed to identify some of the properties of dark galaxies.

Scientists used the long-range telescope at Cerro Paranal Observatory in Chile, which managed to detect gas-rich galaxies that do not contain stars.

So they are looking for the Higgs boson at CERN

You can make the July 4, 2012 in our calendar of scientific milestones. Just presented at the CERN in Geneva, the data of recent experiments in this research center showing the finding with a confidence of over 99% of the so-called "God Particle" or Higgs boson. Mary Chamizo, CMS researcher explains how to get the data and how to seek this elusive particle. Should give the Nobel Prize to Peter Higgs?

Mars Express reveals that Mars has a "complex geological history"

The Mars Express space probe has discovered a wide range of tectonic features and their impact in a volcanic region of Mars reveals that the planet has "a complex geological history." probe photographed last April Meals Dorsa, a volcanic region of southern Valleys Mariners canyon regions located between the Sinai and Thaumasia Plana, reported the European Space Agency (ESA) in a statement.

Chilean worries mysterious streak of light

Around midnight, it was noted 'a very striking light' in the sky of Iquique,
The Committee for the Study of Anomalous Aerial Phenomena initiated an investigation

The past midnight across much of the sky of Iquique, which many photographed, but that could not be picked up by radar and control towers.
Authorities are investigating a mysterious trail in Chile last midnight light that crossed much of the sky of Iquique in the north,

Venus, Jupiter and Aldebaran in the sky line up in July

The two brightest planets in the solar system, Venus and Jupiter will shine together in the sky at night and the dawn of the first weeks of July , as reported by NASA. To observe this spectacle experts have pointed out that one need only look to the east. On Wednesday, Venus became visible for the first time, going through the exact center of a large group of stars that is located 153 light years from the Earth (the cluster of the Hyades). Thus, in the coming days, if you use binoculars, you can see by the planet dozens of stars scattered in the sky.

The day of the year when the Earth is farther from the Sun

There was the phenomenon known as aphelion , which occurs each year between March and July 5. This means it is the day of the year when the sun is farthest from Earth.

Although visually it is imperceptible, with a special telescope experts can see that the sun looks smaller. Precisely, is 3 percent less than its normal size.

According to experts, the effects of this are changes in the tides and a possible decrease in solar energy , but has no effect on the climate, or severity of the Earth.

A hidden ocean on Titan

The Cassini has shown that Titan, a satellite of Saturn, experiences significant tidal effects on its surface. In the course of its orbit, which lasts 16 days, changes shape: the closer is the gas giant tends to of a rugby ball while closer to a sphere at the farthest point from Saturn. This variation leads to a redistribution of mass and a change in the gravitational field. This is what Cassini measured, thanks to whose data has been concluded that in order to explain the tides experienced, Titan must have a liquid ocean, probably water under the surface.
