3 big stories you might have missed on Tuesday, Feb. 6,

Marijuana legalization faces hurdles in the Canadian Senate, SpaceX launches a new megarocket and Saudi Arabia donates $1 billion in aid to Yemen despite conducting airstrikes against the country.

1. Marijuana legalization speedbump

The federal government says it's on track to legalize recreational pot in July, but senators don't appear to be in any hurry to pass the legislation.

Conservative Senate Leader Larry Smith says his senators won’t obstruct Bill C, but will insist on rigorous and thorough examination of the legislation. Health Minister Ginette Petitpas Taylor says the Senate would have to pass the bill by no later than the end of May to meet the July 1 deadline.

2. SpaceX launches car into space

SpaceX's new megarocket launched on its first test flight Tuesday from Florida's Kennedy Space Center as thousands jammed surrounding beaches.

The Falcon Heavy has three first-stage boosters, strapped together with 27 engines in all. The Cargo? In a bit of cross-marketing, Elon Musk, the owner of Tesla and SpaceX, put his own cherry-red Tesla Roadster on the Heavy's inaugural flight with a space-suited dummy at the wheel.

3. Saudi Arabia sends aid

Saudi Arabia says it has spent nearly a billion dollars in aid for Yemen and plans to spend another $ billion, but the Saudi-led coalition against Yemen's Shiite rebels, known as Houthis, has been a major cause of the country's humanitarian disaster, rights groups say. The kingdom's devastating air campaign repeatedly has struck markets, medical facilities and civilian targets -- drawing international criticism in the process.

Sacred Space Astronomy

Saturn, Mars, Jupiter, and the bright stars Antares and Spica all adorn the southern predawn sky. The Moon will be joining the party for the next several days - appearing near Jupiter on the 7th, between Jupiter and Mars on the 8th, and close to Mars on the 9th.

This same region of the sky looks very different when viewed from the southern hemisphere; the image below is seen from the perspective of the Perth Observatory in Australia.

The Moon

The Moon put on a great show during the total lunar eclipse last week; Jason Major took this beautiful moonrise eclipse image:

The Moon is a waning gibbous and will be at third quarter on the 7th. The Moon rises around midnight, and sets around noon.

This weekend the Moon will be a waning crescent, rising a few hours before dawn, and setting in the afternoon.

The Sun

The Sun has a spot! A rather large and enthusiastic spot - which is a surprise since the sunspot cycle is heading towards solar minimum. The composite image below shows a close-up of sunspot AR with very active coronal loops.

vvjstudio.com says: "AR has a primary dark core larger than Earth with many smaller magnetic condensations trailing behind it, in all stretching more than 75, km across the sun's surface. Rare "solar minimum sunspots" are capable of intense explosions just like sunspots during more active phases of the solar cycle. At the moment AR is crackling with minor B- and C-class solar flares, notable only because of the sun's recent tomb-like silence."

There continues to be large coronal holes at both of the Sun's poles. The coronal activity of AR can be see on the left of the image below. vvjstudio.com says: "Solar wind spilling down from this northern coronal hole is brushing against Earth's magnetic field today." The solar wind speed is km/sec, with a density of protons/cm3.

Eclipses

There will be a partial eclipse of the Sun on February 15th, but you will have to be in Antarctica or South America to see it.
