NASA for You

Occasionally closer to Earth appear some comets or asteroids, what can disturb or destroy our daily life.

NASA is in research of person, who would be capable to land on asteroid.

Above mentioned celestial body asteroid, which has got name Aphofiz, is in interplanetary matter race with speed 50 thousand kilometers per hour.

And can collide with Earth on 2036. It can destroy all world.

They think that we have to land someone on it to make a huge explosion there, before time?.

Asteroid Apofiz Can Collide With Earth in 2029

Asteroid Apofiz-99942 could collide with earth in 2029 according to a Russian scientist. Could this happen and fulfill Wormwood of Revelation 8?

An asteroid could collide with the Earth in 2029, a Sergey Smirnov, a senior researcher at the Pulkovo Space Observatory, told a press conference in Moscow on Thursday, Interfax news agency reports.

On April 13, 2029 the asteroid Apofiz-99942 will be at its closest distance to the Earth for 200 years, Smirnov said.

The asteroid will pass the Earth at a distance of 30,000 to 40,000 km. “This crosses the geo-stationary orbit, where all the telecommunications and a lot of military satellites are,” he said.

Whatever happens, the Earth will feel the effect of the asteroid, and in the worst case, it will collide with the Earth, and at best it will damage equipment in space in the geo-stationary orbit.

Hubble makes 3D dark matter map

Hubble's new 3D map shows the "clumpy" nature of dark matter

Astronomers have mapped the cosmic "scaffold" of dark matter upon which stars and galaxies are assembled.

Dark matter does not reflect or emit detectable light, yet it accounts for most of the mass in the Universe.

The study, published in Nature journal, provides the best evidence yet that the distribution of galaxies follows the distribution of dark matter.

This is because dark matter attracts "ordinary" matter through its gravitational pull.

Scientists presented details of their research during a news conference here at the 209th meeting of the American Astronomical Society (AAS) in Seattle, Washington.

It involved nearly 1,000 hours of observations with the Hubble Space Telescope.

For the first time, we can see what's really out there

Prof Carlos Frenk, University of Durham

According to one researcher, the findings provide "beautiful confirmation" of standard theories to explain how structures in the Universe evolved over billions of years.

Ordinary matter - gas, stars, planets and galaxies - makes up just one-sixth of all matter in the Universe. The remainder is unseen.

While previous studies of dark matter relied on simulations, this one details its large-scale distribution in 3D.

For astronomers, the challenge of mapping the Universe has been described as similar to mapping a city from night-time aerial snapshots showing only street lights.

Dark matter is invisible, so only the luminous galaxies can be seen directly. The new images are equivalent to seeing a city, its suburbs and country roads in daylight for the first time.

Yet puzzling discrepancies remain.

Light bending

The map of mass distribution is based on measurements of about half a million distant galaxies.

Lead author Richard Massey and his colleagues used a technique called weak gravitational lensing to detect the dark matter.

To reach us, the light from galaxies has to pass through intervening dark matter.

The study traced subtle distortions in galactic light

We have to leave Earth

Steven Hocking has announced that we have to colonize our lives to usable planets outside our Solar System.

If humans will use now days rockets, then travel time will be approx. 50 000 years, but it is too long and not useful.

In such a case Hocking offers to develop idea of warp drive, which theoretically, will help to get anywhere in one moment.

Is it in conflict with law, that doesn’t allow moving faster as light?

By his opinion we can not break this law by using matter/antimatter annihilation.


Vernal Equinox

Spring Equinox

An event that occurs once a year, when the Sun reaches a point in the constellation of Pisces.
