New evidence suggests a ninth planet lurking at the edge of the solar system Astronomers say they have evidence of a ninth planet in our solar system. Here's what they say they know about it. (Joel Achenbach,Gillian Brockell/The Washington Post) Astronomers at the California Institute of Technology announced Wednesday that they have found new evidence of a giant icy planet lurking in the darkness of our solar system far beyond the orbit of Pluto. Their paper, published in the Astronomical Journal, estimates the planet's mass as five to 10 times that of the Earth. Instead, they have inferred its existence from the motion of recently discovered dwarf planets and other small objects in the outer solar system. Telescopes on at least two continents are searching for the object, which on average is 20 times farther away than the eighth planet, Neptune. [Q&A: The ‘Pluto Killer’ who thinks he’s found the true ninth planet] Confirmation of its existence would reconfigure the models of the solar system. [Is there a Planet X, a ‘massive perturber,’ hidden beyond Pluto?]
Elementary Lesson Plan about the Solar System A Study of the Size and Scale of the Sun and Planets This lesson for late elementary students (grades 3 - 5) teaches about Earth and Space science using an inquiry approach. It covers objects in the sky and changes in the earth and sky, as students learn the size of each planet, the vastness of space, and some special features of our solar system. After this lesson, students will be able to: Demonstrate knowledge of the solar system by arranging spherical objects of different sizes in an order that represents the eight planets and the sun. Prior Knowledge: Your students should be at least somewhat familiar with the concepts of volume and mass. What You Need: Lesson Model: 5Es ENGAGE: Before the lesson, gather household items such as a ping-pong ball, tennis ball, inflated balloon, grapefruit, glass marble, small pebble, etc. EXPLORE: Tell the class that the sorting they just did is similar to how a scientist would classify the planets.

Planeetat ja Pluto | Opettajalle | Oppiminen Aurinkokuntaamme kuuluu kahdeksan planeettaa; Merkurius, Venus, Maa, Mars, Jupiter, Saturnus, Uranus ja Neptunus. Kaikki planeetat kiertävät aurinkoa lähes ympyränmuotoisilla radoillaan. Kaukaisin planeetta, Neptunus, sijaitsee 4500 miljoonan kilometrin etäisyydellä Auringosta. Yhdeksäntenä planeettana pidetty Pluto menetti Kansainvälisen tähtitieteellisen unionin äänestyksellä planeetan statuksensa vuonna 2006. Merkurius Merkurius on Aurinkoa lähin ja pienin aurinkokuntamme planeetoista. Venus Venusta sanotaan Maan sisarplaneetaksi, koska se on vain vähän Maapalloa pienempi ja käy planeetoista lähimpänä Maata. 1980-luvulla amerikkalainen Magella-avaruusluotain kartoitti Venuksen pintaa tarkemmin kuin koskaan aiemmin. Maa Maapallo tai Tellus on aurinkokuntamme kolmas planeetta Auringosta lukien. Maa planeettana Maapallon rakenne on kerroksellinen, sen kiinteä ydin muodostuu pääosin raudasta ja nikkelistä. Mars Jupiter Jupiter on suuri kaasupallo, joka koostuu yli 90-prosenttisesti vedystä.
SpaceWeather.com -- News and information about meteor showers, solar flares, auroras, and near-Earth asteroids Note-Taking for Different Lecture Styles So, when I entered college, I was amazed at how many different lecture styles professors could have. Some used PowerPoints, some used the white board and some just talked at you and expected you to learn that way. Actually, now that I think about it, maybe amazed is not the right word. Maybe it’s better put as “culture-shocked to the point that required me to up my note-taking game.” Regardless of the word you choose, there will eventually be a point in college (or grad school) where your regular note-taking style just can’t efficiently sort through the information presented to you. Therefore, I have decided to write a post that talks about how I adapted with each lecture styles in order to take the most efficient notes and ultimately determine the important test-worthy information. I disclaim that this post presents only tips that work for me. The PowerPoint Lecture. Block of Text PowerPoints So, lucky, a lot of professors know NOT to do this. So, what do you do?

Katso huikea video Lapin tulipallosta – Putoamisalue ehkä Inarijärven eteläpuolella Ursan mukaan tulipallosta on voinut syntyä esimerkiksi avanto järveen. meteorit 17.11.2017 klo 11:41päivitetty 18.11.2017 klo 12:15 Lapin taivaalla torstaina näkyneen tulipallon mahdollinen putoamisalue on Inarijärven etelä-kaakkoispuolella, arvioidaan Tähtitieteellisestä yhdistyksestä Ursasta. Meteorijaoston vetäjän Jaakko Visurin mukaan tätä tarkemmin putoamisaluetta ei voida vielä määrittää. – Näköhavaintoja on tullut Taivaanvahtiin muutamia kymmeniä. Yhdistyksen Taivaanvahti-palveluun (siirryt toiseen palveluun) tuli torstaina niin paljon käyttäjiä, että koko palvelu kaatui. Ei elokuvamaista kraatteria Mitä jälkiä maahan osuneesta meteoriitista sitten voisi jäädä? – Todennäköisin iskemän jälki on pyöreän avannon löytäminen järvestä, eikä kengänjälkiä ole ympäristössä, miettii Visuri. Jos tulipallo on iskeytynyt maastoon, ei siitä jääneitä jälkiä välttämättä huomaa mitenkään. – Se uppoaa maastoon, eikä siitä synny mitään elokuvamaista kraatteria, jossa hohkaa kivi pohjalla ja savu nousee.
