UPDATE: "Halloween pumpkin" video and images from Calar Alto

PortadaThis is an update from previous new. As told yesterday, an international group of researchers have observed the 2015TB145 NEO, also known as "The great Halloween pumpkin" with the 1.23m telescope and with PMAS instrument at 3.5m telescope. Here you have images and the video of the observations.

A group of researchers will observe "The great Halloween pumpkin" from Calar Alto tonight


The nights of October 30th and 31st are the best opportunity for studying this asteroid, which characteristics points that it could be an extinct comet.

The asteroid, with 400 meters wide, will be at about 480.000 km from Earth at its closest approach.




Infrared ‘eye’ arrival completes CARMENES instrument, which will see its first light in November

nir1CARMENES, a spectrograph that will search for earth-like planets, is a unique instrument due to its stability, very high resolution and because it will observe at the same time in both the visible and infrared channels.

The infrared channel, developed at the Instituto de Astronfísica de Andalucía (IAA-CSIC), will be tomorrow placed in its final location, at the 3.5m Calar Alto Observatory telescope.



Calar Alto Observatory in the European Night of the researchers


As it happened in 2014, Calar Alto Observatory has participated on the European Night of the researchers that took place last September 25, 2015.This year the participation consisted in two activities held in the Junta de Andalucía's Govern Delegation in Almería.



What is a lunar eclipse good for?


- The moon darkens considerably during eclipses, which offers a unique opportunity for observing impacts against its surface.

- Researchers from the Instituto de Astrofísica de Andalucía (IAA-CSIC)  have programmed moon observations from different places in order to detect and study impacts on the moon during next September 28th eclipse.

- The most sophisticated observations will be carried out from the Calar Alto Observatory 3.5m Telescope.




A complex maneuver allows CARMENES instrument having its visible channel eye


Yesterday the visible channel was integrated into the spectrograph, a complex maneuver successfully achieved.

3.5m telescope access doors became yesterday small. One of the giant eyes with which CARMENES instrument will search for planets like ours, were successfully integrated after flying, held by a crane, to a height of over 30 meters, entering through the dome hole to reach its final location.



CARMENES, the instrument that will search for Earth-like planets, starts its assembly at Calar Alto

feCARMENES front-end, the part which connects the instrument to the telescope, collects the light and injects it into the fibers, is being integrated.

This is the first big subsystem arriving at the observatory, where the tests will be carried out during this week. 

Almería, April 30th, 2015Before the end of this year, CARMENES instrument will open its eyes which to observe the sky in both the visible and the infrared, searching for Earth-like planets, one of the actual challenges of present astrophysics. During 2015 will happen a series of milestones starting this week with the integration of the instrument front-end, the part that connects the instrument with the telescope, collects the light and injects it into the fibers.
