NASA's Spitzer Space Telescope discovered in Ouumavama in 2017
In November 2017, scientists NASA's Spitzer Space Telescope pointed to the subject of the first known interplanetary space called Oumuamua in the solar system. Infrared Spitzer worked on many telescopes after detecting in October.
Two months after the closest approach to Earth by the beginning of September, Olomoum was very tired to find Smiszer. However, "non-detection" gives a new limit to how big the odd thing is.
A study by NASA's Jet Propulsion Laboratory was conducted in a new study published today in the astronomical journal.
The new size limit has been matched with the findings of research papers published earlier this year. & # 39; s speed and direction & # 39; Small changes have been responsible for the same as last year's tracking. The authors of this article acted as if the gas released by a small margin was slow.
It is relatively small compared to the Solar System comets. ("Suggested that there is a cold gase such as a comet about the production of the vow).
David Trilling is an astronomer at the University of North Arizona. David Triling said: "It was a surprise for me one day from Omuva that we really wanted to know what Spitzer was." Ouuamua is very effective in finding Spitzer. "
The Pan-Starr 1 Telescope of the University of Hawaii at Hawaii, Hawaii, was first discovered in October 2017, the word in Hawai'i meaning from the word Hawai'i. In October 2017, the telescope has been described as the astroydrops.
The subtle observations of NASA's numerous Hubble telescopes and the NASA's Hubble Space Telescope have come from the surface of the drain & # 39; Reflecting sunlight. The large changes in the brightness of the object are the long-running ammonia (2,600 feet or 800 meters).
But the asteroids track the comets using a spitzer, infrared energy or heat. More accurate information on the size of the objects will be provided than the sunlight observation from the sunlight.
Dumbster is worried about Spitzer's discovery in determining the limit on the surface of the object. However, since the non-detection can not form, the size limits will be presented if the Oruva radius is spherical.
The size of the sphere of the Spitzer's non-detective limited sphere, 1,440 feet (440 meters), 460 feet (140 meters), 320 feet (100 meters). A wide range of results & # 39; About & # 39; s draft structure & # 39; From the assumptions, the influence of how much Spitzer is visible (or faint) is a specific size.
Small but reflective
A new study is more than 10 times more reflective than comets in our solar system. An amazing result, according to newspaper editors.
Because infrared light produces large amounts of radiation produced by "warm" objects, a comet or asteroid can be used to determine the temperature; That is, it can be used to determine the reflector's surface – scientists call albedo. Because dark t-shirts in sunlight are faster than a light, the more reflective substance reflects a high reflected object. So the lower the temperature is the more albedo.
A comet's albedo has a lifetime change. When closer to the Sun, a comet's ice sheets directly on the gas, dust and comet appear on the surface of the comet, and the more reflective glaciation appears.
The telescope flowed from the surface and the telescope. But even though it is the closest approach to the Sun, its surface is more intuitive than its five weeks before its discovery. In addition to dust and dirt repression, the ohmuuma may have been included with the coat that reflects some of the gases out of the tropical surface reflecting ice and snow. This is a phenomenon that is found in comets of our solar system.
Our location is from our solar system. It is far from the Sun to the orbit of Saturn. Beyond any other telescope and beyond.
"Normally, if we get a measure of a comet, we will see and re-measure until we discover what we're seeing," said David Fernachia of the Center for Near Earth Object Studies (CNEOS) at JPL. One of the two papers is a coat hoard. "But this is eternal, we know that we know."
JPL Spitzer Space Research Institute (NASA) is headed by the Spitzer Space Telescope mission in Washington. Science works at Spitzer Science Center in Kali, Pasadena, California.
The spacecraft is operated by the Loroad Martin Space Systems company, Laverded Martin Space Systems Company. The information is stored at IPAC in Kalotech Infobox Science Archive. Caltech controls JPL for NASA.
