HUBBLE DETECTED WATER IN FIVE EXOPLANETS

These are great news for astronomers and particularly astrophysicists.

Using the Space Telescope Hubble, to teams of scientists from NASA and the University of Maryland were capable to detect the presence of water in five exoplanets.

Those are WASP-17b, HD209458b, WASP-12b, WASP-19b and XO-1b. The signals receive are not all equal. The stronger signals indicating the presence of water has been detected on.

 "We're very confident that we see a water signature for multiple planets," said Avi Mandell, a planetary scientist at NASA's Goddard Space Flight Center in Greenbelt, Md., and lead author of an Astrophysical Journal paper, published this week describing the findings for WASP-12b, WASP-17b and WASP-19b.

"This work really opens the door for comparing how much water is present in atmospheres on different kinds of exoplanets, for example hotter versus cooler ones."

The studies were part of a census of exoplanet atmospheres led by L. Drake Deming of the University of Maryland in College Park. Both teams used Hubble's Wide Field Camera 3 to explore the details of absorption of light through the planets' atmospheres.

El HUBBLE DETECTÓ AGUA EN CINCO EXOPLANETS


Esta es una gran noticia para astrónomos y particularmente astrofísicos.

Usando el telescopio espacial Hubble dos equipos de científicos, de la NASA y de la Universidad de Maryland, fueron capaces de detectar la presencia de agua en cinco exoplanetas.

Ellos son WASP-17b, HD209458b, WASP-12b, WASP-19b and XO-1b. Las señales recibidas no son todas iguales. Las más fuertes indicando la presencia de agua fueron detectadas en WASP-17b y HD209458b.

“Tenemos mucha confianza de que vemos una rúbrica de agua en múltiples planetas” dijo Avi Mandell, un científico planetario en el Centro de Vuelos Espaciales Goddard de la NASA, en Greenbelt, Maryland, y principal autor de un artículo en el Astrophysical Journal publicado esta semana describiendo los descubrimientos en WASP-12b, WASP-17B y WASP-19b.

“Este trabajo verdaderamente abre la puerta a comparar cuánta agua está presente en atmósferas de diferentes tipos de exoplanetas, por ejemplo los más calientes versus los más fríos.”

Los estudios fueron parte de un censo de atmósferas de exoplanetas, liderado por L Drake Deming de la Universidad de Maryland en College Park. Ambos equipos usaron la Cámara 3 de Amplio Campo para explorar los detalles de absorción de la luz a través de las atmósferas de los planetas.

THE THOUGHT OF Vicente-Juan BALLESTER OLMOS

What a person thinks is important when that person speaks about what he or she knows well.


But when the distinguished Spaniard Mr. Vicente-Juan Ballester Olmos speaks, it is most than relevant, because he is a seasoned investigator and student of the UFO subject. 
 V-JBO has dedicated his life to the phenomenon acquiring the experience and expertise only reserved for the few. 


Currently he works on his Project FOTOCAT, a selective world catalog for the classification and analysis of presumed UFO photos.


That is why so important to know what he thinks about the whole issue and the way it is treated in general.


Those who are newcomers in this field should pay great attention to what VJBO says, because they need to learn, and nothing is better than to learn from those who know what they are talking about.

The attitude of the people in general

"Commonly, people are ignorant of the appearance of astronomical bodies and may be surprised by the view of planets and stars. Probably, predisposition helps, if not other factors. As a matter of fact, the files of UFO investigators are filled with observational trash, misinterpretations and oversights, not to mention hoaxes, fakes and frauds."

Scientists and military don't know basic things

"In Chile, there has been done an extraordinary work of private investigation around the confusion with airplanes or contrails that have been taken by presumed UFOs. Those are observations that should never be part of a list of UFO cases, but which even the meteorological, military and scientific authorities have not been capable to clarify adequately.  


If at this point the investigators who have enough formation and resources are incapable to see in some images that they are dealing with simple condensation trails and airplane lights, who can believe that someday Ufology would be taken seriously?"

The quality of the information
 
"Generally, the quality of UFO information is not as good as it should be. Sometimes it is difficult to check and verify facts, hence the high proportion of sighting reports branded as insufficient data".

The cyber-"UFOs"

"New digital cameras produce splendid, immediate images you can download, transfer, modify, enhance, etc. But the technology involved also provides a brand new sort of imaging artifact. Those unreal images are taken to be UFOs by ignorant or simply credulous ranks.

Basically, the common denominator in the spurious images is that nothing strange was observed visually at the time of the snapshot. In digital imaging, the Charge-Coupled Device (CCD) is the image sensor. When you focus the sun or a very bright source of light, the CCD is over-burnt by the excessive illumination input and it manages to create false –i.e., surreal– black orbs where the light density is greatest, that is, at the center of the radiant body."
